Just a quick thank you...    I'm thinking of starting to use a dual amp setup (5150 + Engl Savage 120 sounds awesome :-) ), and had been checking the RG Keen schematic yesterday. If I want an A/B/Y this layout will be handy... thanks!
How do you power yours?

xshredx-
just wanted to let you know that I'll be re-arranging this layout soon so it's not so cluttered in the lower-left portion.  And it is unverified so far... it should work, but it is untested.

I haven't built it yet, so I haven't powered it.  I've been looking at RG's Spyer isolated power supply for a while now, and I'm thinking that using two leads from that would be a good way to go.  I don't really know... I would assume that two seperate wall-warts would work fine, and two seperate batteries should work well, too.

PLEASE NOTE: As per the schematic, connect the other two leads of the two power sources (ie, the - terminal of the +9v source and the + terminal of the -9v source) to eachother, and both to ground.

cheers,

What does transformer isolation do for the circuit?

What does transformer isolation do for the circuit?

it prevents ground loops from occuring between two different amps or possibly, between the amps and your effect pedals
