*** Old version seen below, new version here: ***

This is the first design I've finished.  It gives a good solid overdrive/distortion depending on how much you turn up the gain.

Amplifier Discussion / What have you guys built?

I finished my TDA2003 amp yesterday (pics coming soon)

So here is my list

2x little gem (lm386 amp) 1/2w
1x TDA2003 5w
1x lm1875 2x20w
1x lm3886 1x50w

Eventually I may build a bridged parallel lm4780 which would yield 200w!!  But for right now 50w is plenty, that thing is loud!
Preamps and Effects / Anyone good at making PCBs?

I have a preamp I want to do.  It is the preamp off a Dean Markley K-20X.

Here is the schematic:

I actually just need someone to make the PCB design, I was going to have 5-10 of them printed by a place online.
