Just checking to see if anybody would like a new design of SECA power amp I am thinking of doing with a on board on Power Supply Regulated/Tracking.
I am think same PCB will do 20W to 35W just bigger heatsink and transformer, it will not be cheap sorry I will be using 4oZ Cu PCB PTH. Designed to fit a a Mod shop case. Not SMD.
FEEDBACK WELCOME

No. Not quite.
Something I keep meaning to ask: how low a damping figure is OK? I was pretty astonished when you said what it was for your design.

What is a ball park figure for completion cost?
I am quite tempted, as I fancy a DIY project for winter.
