Also, try tweaking the 2101's distortion volume & power amp's volume settings to maybe get a more controlled response.
I've even had a loose ground or ultra gainy pickup in my guitar that gave me feedback & squealy noise.
Just some of my experiences with my 2101 I've had for almost two decades. Hope some of this helps....

So would you think that replacement tubes would cure the squealing noise? It seems like applying gain to the 2nd tube causes it more. I suppose the original tubes need to be replaced regardless after ~15 yrs.

I concour with Graham, Doug's Tubes is an exellent and reliable source or tubes.
Doug actually made up a 'sampler set' for me so I could try different brands in my 2101 and select the tubes that worked best for my ears.
Go with your ears dude, they don't lie (at least to you!!! LOL!)

Regarding a source for 12AX7 tubes, I repeat my
previous recommendation, Doug's Tubes:
http://www.dougstubes.com/preamp-tubes/12ax7-ecc83-7025.html?limit=all
Doug has sold me a bunch of tubes for my Randall
RP2/50 and RM4 setup and he's always been dependable, honest, and ships
promptly.

I see that its possible that your 2101 might sound different from another 2101 by doing it this way (not necessarily bad?). If it means that slight gain adjustments might have to be made between units I might be able to live with that. I only really use my 2nd unit as a backup.
