I want to rebuild my 6G3 clone, minus its tremolo circuit, with a new board and a revised grounding scheme. I created the illustration with the DIYLC program from Hoffman Amps/EL34 World. I would like if anybody could take a look at the illustration and evaluate the layout.
The brown resistors are the Vishay PR series metal films. All other resistors are Xicon carbon films, except for the pink colored Takman's. Coupling and tone caps are Vishay Mkt 1813's, filter caps are F&T's, and bypass electrolytics are Spragues. Trannies are from Modulus Amplification, and the PT with a GZ34 is creating a B+ of about 435v with the plates at about 430. The red colored box is a mini board that reduces the B+ by about 50v, and brings the B+ down to about 380v and the plates down to 375v.

Re: New Layout for my 6G3 Clone
Since no one has yet commented on the layout, I’m going to assume that all should be good to go. The adjustable fixed bias circuit was my main concern. I think I’ll flip the location of the V1 grid resistors at the socket and moved them to the jacks. In a couple days I’ll submit a custom turret board order with Hoffman Amps.
