80% PT taps (lower B+) anyone using this for VH tones

Post by awangotango » Sun Nov 05, 2006 3:15 am

I've got a new VH clone i put together with Georges Power tranny that has the 80% taps. I'm getting 420 B+ (2 tubes pulled -should be a little lower with all 4 i think) . Haven't even played the amp at full volume yet so not sure what to expect. I've never had a superlead with voltage less than 460. This amp is my attempt at VH tones, with the merc 0100jm OT and all the little tweeks mentioned on the forums: split cathode with .68uf/1k on each channel, 630 bright mixer, 220ufV2a, .68/4.7k presence, 100pf antifizz, caps under the chassis, 32pre,32screen,100mains, 50 PI. So the only real variable left to decide on is the B+, the full taps will give over 500. Just wondering if anyone gets VH tones with a 410-420 B+ ?
