What everyone else said.

The only 'bummer' i see about re-tubing that amp, is the same bummer I see with all the other amps with 811's, or 572's mounted horizontally;

The modern chinesium tube plates all seem to be made as thin as aluminum foil these days. Those plates melt much quicker and easier. And if horizontal, they might sag into the filament easier. But if it was me, heck yeah --- I'd go for it anyway!

She oughta clean up real nice!


My solution to the missing input network on the Gonset GSB-201 I'm restoring, was to install a cheap N7DDS ATU-100 tuner in it.... Hey, not a biggie and it werked. But you can always just slap any 100W tuner inline with it's input and do the same thing.
