The data sheets are out there and have a basic power amp schematic on them. I have not heard of any amps using them but they show promise. Good luck.

Ok
Thanks for confirming that for me. In the past I have chased down things like this only to find out that everything was fine. It was just not designed like I would have designed it. I did find one bad diode in the switching circuit it acted the same as it did before so I was not sure. I guess I have some more digging to do.

A friend just gave me a Fender ultra chorus. It needs new speakers and he goofed around in side but , otherwise  its in great shape. My question is does this thing turn on with the distortion channel on with out a jack plugged in and then switch to clean when you plug a guitar in it? I has the 9 pin switching jacks and it does ground the channel switching circuit  when you plug a guitar in. The switch on the panel works and a foot switch works. So everything seems normal.

Hi guys!
Well I just started making pcbs and I am looking for one that I can etch for a gainclone power amp. I know I can make one on vero but I am not a fan of the stuff.
Does anyone have a layout they can share or can any one tell me how to add an LM3857t to eagle.
