I just got a Yeti 50w kit to build up. I have a ****** OT & PT from a 50w JMP build I never did. It was built to 425V.
Ceriatone lists the Yeti 502 V5 HV @ 407v. I've read people are building this amp with 475V or also seen people with B+ readings in the 500s, so now I am wondering if my PT will be underpowered for this amp. The layout diagram has 700V on the JTM45 PT, I think? (PT pins listed at 350-0-350.)
Is 425V enough? I assume the mod should hold up with stock JMP transformers, given the origin of the mod itself? Would I have enough flexibility to just reduce the voltage dropping resistors if I want to increase plate voltage and tighten the response up?
Ceriatone Yeti 50W with 425V PT?

The amp will work fine with 425v B+. But it will feel tighter and sound stronger with 480 or higher.
