It looks good now. I also found that placing 4.7BG N caps in PS after ea bridge (total 2) improves things. As I mentioned earlier MUR860 might be even a better choice.

Kimber 4TC is $8 USD per foot from Michael Percy. Partsconnexion should carry it too.

Bypassing
Unless I have missed it somewhere, I haven't seen any suggestions for bypassing the 1000 u's with something smaller (or any of the caps for that matter).
With a smaller bypass cap, it may be possible to increase the overall capacitance without the trade-off that Peter has experienced. Any comments? I appreciate that part of the fun with the Gainclone is keeping the parts to a bare minimum but if a small cap can improve the sound.... And while I'm here can somebody tell me if I have to have four wires on the secondary side of my transformers to use two separate bridges. Mine have just three wires.

Bypassing 1000u with 4.7u doesn't seem like increasing total capacitance by much as the intention here is to attenuate diodes switching noise (as suggested by Fred)
 . N type BG also improve the sonic character of the 1000u caps which are standard grade.

do you mean using one wire for each connection? does it have a high enough current rating? if it does, good, because i have about 8 meters of it (i think) (the solid core wire type). [edit]: isnt solid core wire the best conductor you can have? if so, why dont people use bell wire or similar? unless your experimenting alot, your ampa dn speakers dont need to move around alot, so solid core wire should be fine, right?

That's my latest implementation of gainclone circuit. Now my amp has not only 3/4" aluminum front but back panel also. Who else?

No problem. I don't know if it's because of thickness, but it seems to be sounding substantially better than previous version which had only 1/2" panels..
