Is it possible to know TO much about electronics and audio thylantyr? If its possble, I think you do, :p:.

But from what I understood, I don't see why it won't work, and sounds like you sure know what the heck your doing. I demand pics and reviews once it is done!

The main reason for doing it is --> because I can .. and .. I like to drive
the amplifiers lower than recomended 'ohms load' ... and it's general knowledge
that when you load down a power supply the ripple/noise increases so extra
caps would be nice for abnormal operation of the amp to keep the rail voltages
clean and help to minimize sag on transients.

I'm getting in a few more PLX's later this week, I will probably tear one
down to examine the idea more closely but I don't see any issues.

I take it you dont like Crown.... also know as CLOWN Amps....

Crown is cool but lets compare;

Entry level;
Crown XLS - that famous 'Crown sound' one reviewer said, unbeknownst to him
C-Audio designed the amplifiers then Harmon bought them which in turn owns
Crown and next thing you know, Crown has a new XLS line of amps... /rofl

XLS is a good amp for HT because the price is nice and the sweet spot is
the XLS402, for about $250 ... see pics;
http://home.pacbell.net/lordpk/proamp/Crown_402a.JPG

No real heatsinks used, no variable speed fan, and the two fans runs high speed irritating people who own them for home use.

QSC entry level -> RMX
http://home.pacbell.net/lordpk/qsc/RMX2450-1.JPG

.. cost a little more, but you get real heatsinks in a wind tunnel design,
variable speed fan {1 fan!}, more power and the ground collector
design allows the transistors to be shorted to the heatsink with
no insulators, better heat transfer. {PLX does the same thing but different,
took me a minute to figure it out}.

Crown CE series {except CE4000 which is unique},
CE1000 and CE-2000 are nice but look ---> it's a 3RU chassis and the
CE1000 is limited to only ~2kw... QSC RMX2450 is 2RU @ 2400w ...
Crown cost more too! Given today's technology, 3RU isn't popular
for 2kw and under.

Crown XS series? Street price $1100.. I'm not sure if this amp has SMPS
or not, they don't say anything so I assume no... QSC PLX3402 has more
power for $100 more and you get SMPS.

Crown Macrotech? These are old school monsters, very nice, heavy as
a fvck... Touring amps and this classification cost alot more... I like
their 5k model, nice amp, 88 pounds. About $3k new ? QSC has nothing
to offer in this power range unless you count discountinued product :crap:

Crown Micro-tech ? Lets see what Crown has to say about these amps;
http://www.crownaudio.com/amps.htm

The chart has no blue check marks ... ROFL .. good for nothing ? /// hahaha

Crown K series ? This is a nice series, fanless, efficient.. very nice and
people love them for subwoofers. Limited to 2500watts, probably in
the same price range as PLX3402.. But the designer claims he'd never use one
for mids/tweeters, only woofers. it's a mixed review for the top end, maybe
50/50... PLX on the other hand has 99% positive reviews to run this amp for
tweeters/mids, but 50/50 on subs... ROFL... I can know why it might get a bad
rap for subwoofer driving. A.) power cord is IEC 16 awg .. LOL .. users recommend
IEC 12 awg... B.) rail capacitance is anemic {2X less than PL2 series}, 7X less
than my mod :)

Crown I-tech ? These are sweet. 8kw in a 2RU size for $7500 street price.
/sick.. their flagship new touring amp... /sick

What about QSC PL2 series? These are nice but it's a PLX with 2x more rail
capacitance and voltage/current monitoring with dataport, rail voltage slighly
higher for a few more watts... Precision gain knobs. Nice amp, but for home
use there is no need.. PLX is fine amd cheaper.. There are tons of them
sold in the past 10 years making them a classic.. I've been buying them
on the used market, average price $770 plus $25 shipping.

What about QSC PLX2, a new product line coming soon ? This is a funny
amp.. You take the PLX famous design, make a new chassis, add more
rail capacitance, remove the rear dip switch in favor of something more user
friendly and add a crossover. Viola'... PLX2 is born... Rumors -> big price drop!
:unsure: ....

Best bang for buck ~2kw amp -> RMX2450
Best bang for buck ~3kw amp -> PLX3402

my cap modded PLX3402 -> :yumyum:

Wildcard -> Behringer EP2500 if impedance load is light.. [RMX2450
clone with smaller tranny]

Think about system design rather than 1 uber amp.. For instance,
what can you do with a $3500 amp budget ? You can get 1 Macrotech
5kw monster. Or, I can get three PLX3402.. I can do more with six
amp channels vs. two amp channels in a fully active speaker design.

Or... I can get 11 EP2500's... or 8 RMX 2450 ... etc.

Depends on application.... I like the idea of using ten PLX's for $8000
to give me 34,600 watts over an Itech-8000 for $7500. What will one
two channel 8kw amp do for me ? It will save me space, 2RU vs.
10 x 2RU ... but the Crown won't do crap when I need to drive
a 3 way active system with just two channels....:crazy:

This is what will happen.

A. The amp doesn't blow up.
B. The amp blows up.

All you do is make a prototype before production run

Hard to explain. Maybe an analogy.

Your friend goes to music school and knows alot after getting his uber
degrees. You on the other hand focused on what you really like, guitar
playing. After your friend finished school and hung out to jam on tunes,
you realized the he svcks at playing musical instruments because he had
his head stuck in book too much and no hands on experience.. How do you explain this?
It's a balancing act. You need to spend some time in the books and some of the time
working with the hands.

If all goes as planned, year 2007 I will have the system running. The plan for 2006 is
to finish the homestead projects including A/V room {nothing fancy},
mod all those PLX amps, design/build my custom AV cabinet to hold those
amps and sources, take a summer 1 month vacation to chill .... and try to
get the remainder of the tweeters for the project. The next big obstacle is
to get some metal working done, actually re-done as that project worked out
in the end, but wasn't what I wanted in the first place - arg.. more money down
the drain..

I really goofed by posting this idea on the pro audio forum. I thought for sure

Some of their comments are just retarted. There is only one or two people
on that thread with skill in understanding, but they still don't understand :)... perhaps
their heads are stuck in books too much .... or lack of ...

What is the most comical? I've been trolling audio forums for years and years
and oddly enough, the one industry that gets the least amount of audio respect
is the car audio industry.... but yet, when I preach my madness on car audio forums, most of the people can
relate to the concepts in some way or another, keep an open mind.

For home audiophile forums, it's too difficult to remove what they've been taught
by reading stereophile type of magazines and what not. I was expecting the
pro audio folks to be more knowledgable, but they too have their own
audiophile ways and behavior. Interesting though, is certain car audio celebrities
[you know who they are] that have put their name on the line to break all the
audio voodoo that spreads like wild fire in those other industries. Moral of the
story, you can learn alot about audio by hanging out on car audio forums,
but the home/proaudio people will rarely agree... :)

The Pro-PA and Home-Audio world is messed up my friend. There are only a few companies or people out there anymore willing to try new things because most guys that are in that are about as smart as a bag or rocks. All I have to say is thank god for people like John Meyer, John Bowers, D. B. Keele, G. A. Briggs, Bob Heil, and many others. With out people like these guys we would still be listening to crank phonograph players. What drives audio revolutions is to imagine a way to make something sound better, have more functions, be more reliable, and so on. The big 2 in Pro-PA (Electro-Voice and JBL) are now just followers to other companies (Meyer Sound, Martin Audio, Adamson, Nexo, VDOS) who use engineering and logic to make a better product.

Another great thing about audio is there is never a right or wrong answer to most things, it is the ultimate to each his own type situation. People need to understand they DO NOT know everything about audio. Because when someone thinks they know everything they can not learn anymore. People need to be more open to new ideas, topics, or whatever else.

My point being even if you know a lot you have to respect other people that know a lot and be willing to teach the people who don’t. For example, I personally wouldn’t go with quite as big of a system as thylantyr in my house. HOWEVER, I respect him because he is experimenting and trying new things. I bet his system sounds pretty danm good because he has a lot of good ideas. So, keep at it man just don’t go def lol.

On the other hand, on CAF home audio, a small place in cyber hidden from
the masses, I spend my time there posting weird stuff and many times mocking
product for fun. A few chime in on the punishment.. Then you get the people
who counter and don't understand the clowing... Some of the clowning is
for fun, some is for punishment, mix the two and we have funishment.

There is alot of funnay in that forum, but it only goes back a few pages of
history unless you search archives.

Usually, I'm anti-mod because it's retarded because the claims made.
The claims people make are invalid, just personal opinion without scientific test. ie,
I upgraded my CD player components with more expensive capacitors
and the sound was amazing. I say 'prove it with ABX testing'...

When I do a mod, in this case, I'm not making power boost claims like
someone else would do. I'm not saying the SQ is better either. I'm saying
I'm boosting rail capacitance to have more stored energy :) Perhaps improve
ripple and stabilize the rail voltage better under heavy load.

Lucky me, based on experience, I decided to torture the PLX amp on the test bench to get a baseline of what it can and can't do. It would be dumb to
just blindly do a mod, then bench test it without previous data to compare with right?

So.. the drama unfolds... read how the PLX went up in smoke here {before mod}.
http://www.caraudioforum.com/vbb3/showthread.php?t=235998

This is a good lesson for modders. If I were to mod the amp and then run it
through the torture test, it would have blown up and it would have me
scratching my head -> Did the mod do this? WTF ?

Now I have an idea on what the amp can't do well -> continuous sine wave
testing w/abnormal load, but this is no surprise as pro amps aren't really rated to do this, look at
the chassis they are in, it's small. These amps are more for music not playing
test tones and taking torture. There are exceptions to the rule, if you want to
buy a 4RU proamp beast that weights 150 pounds like a Crest 10001.. /LOL

The plan is to repair the amp {parts on order}, redo the test with a normal
load, not abnormal, and see if the amp is happy and take some readings.

Then, make a prototype cap bank that just sits on the test bench and taps
into the rails via wire taps.

Another test/measurement I want to do... I snagged two 30,000uF caps
[200V] to do another experiment on the input power supply {the amp has two
supplies} to make it 'stiffer' {car audio term}... I want to compare voltage sag
with and without the extra input caps. These caps are big, 3" x 9" so they won't
fit inside the amp but I can get some data from it.

I guess I'm just curious on how the switcher behaves under different conditions.

SMPS vs. Conventional Power Supply
SMPS = switch mode power supply aka high frequency switching power suppy, found in
alot of electronics today. Small transformer, high power because the transformer is being
turned on/off much faster than household 60hz AC {switchers for audio can be 50khz - 300khz},
but 100khz plus or minus is more common.

So which design is better? Car audio needs SMPS because the battery is 12v. The SMPS has to support
high current draw, hence you see many parallel transistors driving the transformer. The transformer is
small compared to a traditional 60hz transformer in a conventional power supply.

SMPS has more parts and the transistors are prone to failure if you exceed it's design, in this case
the PLX amp using only two transistors to switch the coil and it went -- kaboom -- during torture.

Conventional supply -> big azz transformer, lots of power supply capacitors, and a few diodes.
Anyone can make this in a garage blind folded, it's that easy. SMPS is not easy to DIY, there is more
science involved to get it right.

A conventional supply is so simply and dumb, fat and heavy that it's really like a tank.. You can abuse
the hell out of these with no issue other than the transformer getting hot, but it takes a long time
to smoke a transformer. If the diodes you uses are beefy, they can take alot of punishment.
Caps really don't go bad if you load down the power supply hard.

SMPS is more sensitive because anything can cause the transistors that switch the transformer
to smoke. Usually one does the 'push', one does the 'pull', but they alternate .. if both are turned on
for whatever reason, smoke.

Even though we like smaller product, lighter weight, sometimes the good old concentional power supply
is just too good to ignore if you design a product to be abused.

Finally got back to the posts and I have one question, did you look at his pictures???? How do we say "amateur" hour? The company I work for got out of the sound reinforcement business because of yahoo's like this one who think they can do a better job with ****** equipment and less knowledge than my right nut, oh and wait charge 1/3 of what the job is worth. I have used better equipment on 70V/140V line dime store paging systems for Sporting and Motor sport events. Too many "amateurs" confuse Curvilinear Line Arrays with the theoretical sense of a Line Array, INFACT a column speaker technically under the strictest of principles is a Line Array (but backwards with a few different parts and terms). In the worlds of Jack Nicholson "Why can't we all just get along?"

Car amplifier have power transistor as the main failure mode.

Output stage - could be bipolar or mosfet transistors, the big ones attached to
the heatsink. They usually short out when blown, sometimes they look charred.

Power supply - 99.9% chance it's mosfet, the big ones attached to the heatsink.
99% chance that if the power supply blows, the whole bank of transistors
are blown as they are in parallel. All it takes is one to fail and that one takes
down the others, people in a boat analogy. One guy cuts a hole in the boat,
everyone sinks. /hehe

If the output stage has a bad transistor, check the small signal 'predriver' transistor
to make sure it's ok. Oddly enough, I never found one to be bad when I did
amp repair and the odds of them going bad too is pretty good.

It's rare to find a 'signal processing' problem.

So.. you need to look up NPN and PNP transistors and how to measure
them with a DMM using the diode check.

Mosfets you can use the Ohms settings.

Also, when measuring transistors in a circuit, the readings can be skewed, ie
hypothetical -> you have four output stage transistors in parallel and you
measure a short. Are they all bad? You don't know because they are in parallel.

Basically, if you find a short, you have to remove all the transistors and measure
them seperately to really know if they are toast.

Transistors can 'open circuit' also which means they are bad but you don't
measure a short. Usually they are shorted.

Another tip. Suppose your power supply is toast, it has 10 transistors. You
are not sure if all transistors are toast, but you find out each transistor cost
only a buck. Well then, buy 10 or more and replace the whole bank, it's
only $10. That eliminates all the doubt.

Then, you have to re-install the transistors back making sure the case doesn't
short to the heatsink as most amplifiers {few exceptions} have electrical
isolated transistors from the heatsinks via mica insulator, but also they have
the white heatsink compound for good thermal transfer.

Never test your amp with transistors NOT mounted to heatsinks. A transistor
case not attached can only dissipate maybe 2 watts. With heatsink, it dissipates
alot more heat. So.. a person doing a repair but didn't attach the transistor
to the heatsink can blow up the amp again.

After you install new transistors, use the DMM to make sure the case is
not shorted to the heatsink.

There are some amps that do have the transistors mounted to the metal
without insulation, you have to look at the mechanical design when you remove
the transistor. Does it have a mica insulator? if not, maybe it's one of those
amps OR .. maybe someone who tried to repair the amp screwed up and forgot
it, hence it ain't working and is toast.

After the repair is done, most people will tell you to use a current limiting power supply
but most people don't have one, instead just install a very low amperage fuse, maybe a
few amps or so to see if the amp turns on without blowing the fuse. If the fuse blows,
maybe the repair is not good yet. If the fuse hasn't blown, perhaps a good sign. Trying
playing tunes with a small speaker at very low volume.

My PLX amp mod idea sure raises hairs on people.

I've been talking to a QSC employee and he thinks -> 'yikes'.

Dan W. raises the eyebrow;
http://forum.carstereos.org/t58418-qsc-plx3402-upgrade.html

... and now on the AVS forum {power supply bone head thread},
someone comes out of the closet and makes his first post telling me
to beware.
http://www.avsforum.com/avs-vb/showthread.php?t=641883

.. not to mention the cold shoulder treatment I got on the pro audio forums where they closed
my thread on the subject.

Party poopers! :moon:

One of the points in doing these experiments is to have first hand data
on how the amp performs under the conditions I give it. I didn't do any
mods yet and I managed to blow up the amp to see how far I can push it.

No big deal, the amp is fixed and ready for action again. I already did the input
cap test, next is output cap test, the one everyone fears and everyone
trying to dissuade me.

.. ok .. for sake of argument .. I do the mod, the amp smokes.. I fix the amp..

I have data now. The amp design can't handle the mod, what's the big deal ?

What if the amp doesn't smoke and runs for months with mod ? Then I know the
amplifier is robust enough to handle the mod, then I mod the rest of them
to have more rail energy storage. /done stamp/ {monster house}.

If people never try things that are 'black sheep', then they'd never learn anything
extraordinary. :crazy:

My PLX amp mod idea sure raises hairs on people.

I've been talking to a QSC employee and he thinks -> 'yikes'.

Dan W. raises the eyebrow;

... and now on the AVS forum {power supply bone head thread},
someone comes out of the closet and makes his first post telling me
to beware.

.. not to mention the cold shoulder treatment I got on the pro audio forums where they closed
my thread on the subject.

Party poopers! :moon:

One of the points in doing these experiments is to have first hand data
on how the amp performs under the conditions I give it. I didn't do any
mods yet and I managed to blow up the amp to see how far I can push it.

No big deal, the amp is fixed and ready for action again. I already did the input
cap test, next is output cap test, the one everyone fears and everyone
trying to dissuade me.

.. ok .. for sake of argument .. I do the mod, the amp smokes.. I fix the amp..

I have data now. The amp design can't handle the mod, what's the big deal ?

What if the amp doesn't smoke and runs for months with mod ? Then I know the
amplifier is robust enough to handle the mod, then I mod the rest of them
to have more rail energy storage. /done stamp/ {monster house}.

If people never try things that are 'black sheep', then they'd never learn anything
extraordinary. :crazy:


I envy your spare time my brother. But atleast you put it toward something interesting I must say.:)

If it was medieval times, we'd be talking about DIY weapons to slay dragons.

Making stereos or slaying real beasts ? I think we missed the boat ...

Moral of the story. The story is still on going but I do show that
people should never assume that highly educated people are smart,
whether it be electronics, fixing your car, solving your health problem, etc.

This is a classic case where engineering folks all agreed that the idea
would fail because they have the 'sky is falling attitude".

A good rule of thumb. If ten people think you idea svcks, then perhaps you
are on to something and pursue it. :crazy:

BTW, the Ology Audio midwoofer project is another example. Industry professionals
said it couldn't be done, yet you saw the new thread they posted .. the teaser pic. Step two for them - get the driver tested and provide data ...
