Dunno how feasible a voltage doubler and a couple of GI7B tubes would be.
The tubes are cheap and it would be an interesting project.
73 and good luck,

I've just gotten this nearly mint and hardly used FL2000 for a song. The
original 6KD6's are nearly new but I would like to keep them for my great
FT-501 with CW filter and very tired finals. Is there some type of
conversion the FL2000 can undergo with another type of tube(s)? It would
be a pity just to gut it because I stole it's tubes! Am I barking up the
wrong tree? Maybe I should retube the FT-501 and use the FL2000??
The FL2000's power supply gives 1200 volts dc. and I can do moderate
circuit modifications to accomadate one or more tubes. Maybe put a doubler
circuit in the H.V. bringing it up to 2400 v. then I could put in 572's or
something else?
Another question: Are the four original 6KD6's in the FL2000 matched ?
73's all
