I only have the OPTs, so I'm going to build mine from scratch with a pair of Stancor 800vct trannies and use a 5AR4 rectifier, which should get me about the right B+.
Also, the W4's arrived today--all original, in very good condition, and all the iron appears to be in good order. They look like factory builds to me, different coupling caps in each one, but the OPTs are Stancors and date-code matched, a big plus! I'll do a full refurb underneath and convert them to the Gillespie EL34 triode version.
