Just changed some tubes in my S-38 and the original 50L6GT was changed
to 30L6GT by my tube supplier. I know that it is the audio output
tube, but listening to it does not seem to make any difference. Is
there a difference? Should I pull the tube and use the 50?
Thanks

Add up the tube filament voltages and see which tube is closest
to what your line voltage. I'd think that the 50L6 would be
preferable.

Tio,
Thanks for the advice. It was a 35L6, not a 30L6, but I put the 50L6
back in, it was not the problem, it was the rectifier tube, don't fix
what works, right?
Thanks
