I did, when I first started swapping tubes I swapped all. 6SH7 did not have any effect.
Also one thing: the chassis says 6AU5GT or 6AV5GA. I have 6AV5GT. Which are the same electrically but are in the smaller envelope I believe than GA.
I think I go buy a pair of either one recommended on the chassis and give it a try.
PS. Bought 6AU5GT, with shipping about 4 bucks a tube BIN.
