[Amps] la-1000 what to convert to?

[Partain, Chuck]

I have a orig la-1000 amp supply laying about and figure for this winter, that might be a good project to tear into. 
Parts collection will start soon. I see a few folks have converted to ceramic tubes, russian glass or whatnot.
anyone do any of these? and what might you suggest is best?

on a REALLY good day I can see ~500w out of the  4 sweeps!!!

1100v at 1 amp I THINK the transformer will do, I don't want to replace it yet.
