[quote author="NewYorkDave"]Circuit ground and chassis ground are connected together at one point only, at the power supply. I thought I made this apparent in the schematic, but maybe not...
There are multiple shield ground points shown: the input and output XLRs, the electrostatic shield on the input transformer, etc. Just connect these to the chassis right at the mounting point. Actually, connecting the input xfmr electrostatic shield to circuit ground instead of directly to the chassis may, in theory, yield some noise improvement, although I didn't do that in the protoype.[/quote]
Excellent. Thanks for the assistance Dave. I should have the wiring done tonight, but I'm still waiting on the tubes... Can't wait to hear how this baby sounds.
Oh, and my power supply section is different from yours, so I haven't really looked over your supply schematic in awhile, which explains why I didn't catch the single ground point.

PS - I also built your re-amping box and it is a great and handy tool for my home studio. I've been a lurker on this forum over the past several month and I gotta say that I think it's amazing how genuine and forthright you are with your help with problem solving and posting designs. I'm a big fan.
