Hi Tre, i could not find the schematic in my files but it is a very basic type. The filament tx is reversed wired to a .8A 6.3v tap, the 120v is FWBR and filtered by a choke about 25H x 715dcr. this voltage is filtered by 50uf x 120v then dropped by 5K 3/4w mf then 50uf x 120v then dropped by 10k 3/4w mf then 100uf x 100v to the 50k AB 2W carbon pot. The wiper is 50k 1/2w cc connected to the power tube grid stopper. The wiper also has a 50uf x 63v connected to it.
Well, i did not have a single 50uf x 120v cap so i series connected 2 63v x 100uf caps, and not remembering that the metal can is "hot" sometimes they were sitting on the chassis. I guess i better change them out. thanks for the help! cheers, Dak
