Hi, I've got a 1965 Fender AB763 deluxe reverb that is running high plate voltage due to today's wall voltage. At 460 plate voltage I'm biased at around 19ma, for 64 percent or so dissipation. I want to bring that plate voltage down as I don't want to shorten the life of these tubes (NOS GE 6V6GTs). I don't want to use a bucking transformer or variac. A lot of people would put JJ 6V6s in there as they can handle higher plate voltage. However I have a question: The power transformer is original Schumacher 025130. I have read contradictory stuff online about what kind of rectifiers the 5v winding can handle. I have seen some that say it's meant for a 2A GZ34, and others that say it regularly shipped in amps that used a 3A 5U4. If this is the case I would rather try swapping out the rectifier to give me around 430 on the plates. Can anyone point me to any definitive info online as to whether this transformer has the current capacity to handle a 3A rectifier safely? Thanks!
