Short explaination. I'm trying to fix the amp -------- harr harr harr

Amplifier repair is like a murder mystery -- who dunnit ?

or in this case --- what-be-broken that I haven't found yet ?

Today, I will install the chips and place the scope to see if I get signal... main screen turn on ... move zig!!!!

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.

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. //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

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. //content.invisioncic.com/y282845/emoticons/crazy.gif.c13912c32de98515d3142759a824dae7.gif

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 ...
