Refreshing to see some real hands dirty engineering and construction here on the DIY forum among all this magic wire talk lately.

Thanks gusser, I thought this would be interesting to share with. I am sure the schematic is not as clear as it should be, and there will be changes as I go along. Most of every thing I have done is like every thing else you see here so this is the first thing that I feel is worthy of looking at.

This was a fun project I have one amp left to compleat. The power output is in exess of 200 watts@ 1K. 1 watt sweeps from 20 - 50K at this point. There will be need of fine tuning (Zobelation)as there is considerable ringing above 10K. I will compleat the schematic in a few days.
