when I unpack my stuff and get an actual shop area that will be the first thing I'll do. But it's going to be a while.
So plate, cathode and grid - basically take out all the metal film and use carbon film.

If you go the fix-it route --- try to mod one section, at a time. That way, if you go further from desired end-point... it'll be easy to reverse the mod. I like starting at input, then phase inverter sections.
IMHO, Wholesale mods are a way to instant insanity.

Right on Steve! I learned that the hard way many years ago.

I can't agree more.
And yes that was the plan. First the invert, followed by the splitter and then the output grids. Most of the time that ONE upstream part is all you need.

The Sylvania 5932 is one of the warmest output tubes of the 6L6 family. In my experience. Max dissipation is around 22 watts per tube, IIRC.
6L6GA are also a bit warmer in the midrange, but have lower dissipation ratings, 18 watts max.
what plate voltage can those stand? I think a vta st70 puts 430-440ish on em.
I'm pretty sure it can use the 6L6. I'll email Bob and ask???
Yeah, best to contact designer or manufacturer of your unit.
Good luck, in the hunt for perfect tone!
