The classic topic, tubes vs. solid state. /lol/

Tube Amp Distortion.

Tube amplifier amplifying a 1khz sine wave.

Clean signal just like a solid state amp.

Tube amplifier over driven into high distortion.

Look at the shape of the sine wave, it's mangled.

Solid state amplifier clipping

The more you over drive the sold state amp the more it starts to look like a square wave.

Here's another where the tube amp is operating cleanly and as you over drive the tube amp,

the sine wave becomes mangled and eventually looks like a square wave if you over drive it enough.

Ohhh man, thanks a lot....

This picture's going to give me NIGHTMARES

Tubes DO sound different than solid state, it's not better or worse just different.
The proper saying is.

Tube amplifiers can sound different or the same as a solid state amplifiers

depending on it's used. //content.invisioncic.com/y282845/emoticons/yumyum.gif.0556df42231b304b9c995aefd13928a8.gif//content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

 
Tubes clip less elegantly than a SS amp....but clipping is crap either way lol.
I would rather have a rounder distortion wave than a square distortion wave. Nothing like throwing DC at your system....

That is the comedy. A low powered tube amp can be over driven easy into

excess distortion. A high powered SS amp will still be operating in the linear

region offering no excess distortion. Even though the tube is clipping more

elegantly, the SS amp offers no clipping. Which is better? /lol

I understand the DC analogy but technically it's not DC. DC = direct current

or constantly flowing. Clipped signal can't be DC, but I've often referred to it

as pulsed DC, but that's misleading too.

On the other hand, lets say you live in the world of Dungeons and Dragons

and you are a Liche Lord and you cast a spell called 'Time Stop', that clipped

signal may be DC for the duration of the spell or does current stop flowing?

:unsure: If current still flows under a time stop condition, then an AC sine

wave could be measured as DC because you captured the voltage at that

particular time and it's held there. /harr harr

It's not DC since the signal is still oscillating.

 
But, it is still flat and constant for a considerable amount of time, which makes it DC. I still call it throwing DC. You can call it whatever you want, but it's still DC. And DC+speakers = bad news...
