I did a fair chunk of research online and found that thread you posted, but it didn't really clear up how capable the transformers were. So im guessing theyre capable of putting out the 100w youd need for a pair of 88s?
Kt77s are kinda the obvious choice, but I liked the idea of the 88s as it means I could get my amp up to 100w with out (hopefully) having to spend so much. Plis 88s are bad ass. I mean, more watts is good watts. Moar is Moar.
I'm quite happy to stay at 50 if there's no possibility of doing it without ponying up for new transformers, choke, additional filtering and having to completely overhaul that section if the amp.
I'm looking at changing the bias resistors anyway, as I don't seem to be getting the right amount of draw for the plate voltage. I have a feeling that that's because the old filter caps may be giving up the ghost, though, and leaking voltage some.
So getting that ship shape is my priority for now.
I do have those thoughts though, you know the ones, "well, while I'm in there, may as well GO TO 100 WATTS AND PUT KT88S IN THE BASTARD."
You know.
Those thoughts.
Edit: I read that again. Slowly this time. It seems doable on paper? With not a whole bunch of changes......
Hmmmmm......
