Thanks for the replies guys... Since I happen to have an EP Booster I'll try it at the end of the signal chain.

Hi... Having just tried going directly from my pedalboard to one side of the power amp, I discovered that it works without a preamp. I got to thinking about it and the 50/50 does have preamp tubes that I assume would accept Hi-Z and line-level signals. So my question would be... after the Hi-Z...

Thanks for your help... Bro! I would've not thought about the preamp tubes without you. We'll see if the fix holds up. :)

I think I got something... the PI tube on one side seemed to be the problem one. I moved the driver tube over to replace that PI tube and put a fresh tube in the input 12AX7, and it appears to have fixed it—no screechy and more balanced output. A couple of rehearsals should test that solution...

...definitely try all of that. I didn't detect any odor though, and although it always has a slight power imbalance when I power it up at home,(always the "right" channel when facing it), I took it to rehearsal and had to crank that channel up to 8 just to match the 3 on the left. I knew...

@Henz; Thanks for the reply and suggestion. I could check the 12AX7s at the inverter stages, assuming that they are the last ones for each channel. Besides checking for the glowing strength against the other 12AX7s, would the idea here be the substitute method? Another clue to the problem that...

Has anyone experienced a power imbalance where one side does not keep up with the other? I've tried switching out the tubes (with others) and those seem fine. I think the amp may have been this way for quite a while. Any thoughts out there as to what the issue might be?
