you'll need 2 walwarts, since digital and analog inputs/grounds are separated.

Glad you solved the problem. That is really a nice amp, one of the nicest I've seen

I don't see a reason why it wouldn't work, the results will depend on type/quality of such PS.

One is OK too, just connect C1/C3 in parallel.

HI Peter
I dont know if is OK if I post here . I purchased from your GC premium kit .I put them together using 2x20V 160VA transformer for each chanel .
I used silver wire with teflon tubing for the signal and for the power I used Kimber 4TC Kable .
It works well but unfortunatly some how I miss the bass .Compare to another amplifiers it sound les dinamic and the bass..... less punch ..
I tought to increase the power supply voltage . I purchased two toroid from same commpany but 2x25V 225VA each .
I intaled the new toroids hope to do some positive , more power or more bass but it get worst .
Yes there is more power but somehow the sound get tinier , it just get lauder with less bass .
I tried to mounth diferent film capacitors or to use larger capacitors insted the 1500MF but did no impruvment .
Do you have some idea why the larger transformers has less bass than the smaller ones .
Both from same commpany .
If you know some good idea how I can get more bass or more punch please let me know .
Thanks Regards
Ya I'm using a Alps blue velvet pot ....

If I may...What kind of speakers do you have? Gainclones are wonderful little amps. But can't drive current hungry speakes well.

That's strange I have built two kits from Peter and used 225VA transformers. What impressed me most was just the deep and powerful bas. I have not earlier been able to squeese much bas out of my Proac Studio speakers. But with the gainclone a wonderful bas was the result. The opening track on Diane Kralls "Love Scenes" has a deep bas intro. You have to hear it to believe it I built the kit without any modifications. Hope you will sort this out because the gainclone is a lovely amp. It replaced my modified Dynaco ST-70 and PAS3 preamp with good margins.
