Solid State Amp design literature/informative websites?

[drummer4gc]

Hi all,
I've been playing with/fixing/building/breadboarding stompboxes for awhile now, and I'd like to learn more about amplifier circuits to extend my hobby a bit. I feel like there is plenty of information out there about tube amp design and circuitry, but I haven't found as much about solid state amps. I guess I'm mostly interested in power amp design, as the preamp circuitry seems to mirror a lot of what I have already learned about effects circuits.

I think many newer SS amps use chips for their power sections, but I have owned/come across many vintage amps that use power transistors. Does anyone have any good resources for learning more about these designs to aid in maintenance, repair, and tweaking?

Thank you!

For power amplifiers:

This book covers a lot:
Audio Power Amplifier Design Handbook (Third Edition)
by Douglas Self

There's also many articles in Wireless World
Some here,

and some here

and

There's too many.

I've never built an amplifier (in sense that we're talking about here), but if I did, I'd have to list Rod Elliott in my acknowledgments.  So much great info on everything audio electronics related:

Chip-amps (like the much used TDA series) are essentially a "opamp" poweramp (somewhat like the Self's "blameless") in-a-chip, meaning you can learn much about amps just playing with these chips. Things like loading issues, NFB tricks, designing a bulletproof interfacing to other components, designing a Zobel network etc.

Of course, designing and/or troubleshooting a discrete power-amp's innards is "something completely different".
