I'm experiencing the same problem. I was getting a constant hum from the right channel of my OTL amp. I took it in for repair. Apparently one of the capacitors (there are 2 per channel on my amp) on the right side had gone bad and needed replacement. After replacing the capacitor the hum went away but, I started to notice this ever so slight loss of gain from the right. I tried the tube switching but without success. What could be causing this? Hope someone can shed some light on this. I know it's not my preamp because I was able to try a different amp last night -- there were no loss on right channel.
Lower gain in left channel.
I just noticed last night that the volume from my left speaker is lower than my right speaker. It is enough that images are pulled towards the right speaker, but it is not glaring. Could this be a sympton of a power tube going bad? I'm running An Air Tight Preamp (with 6 month old new tubes) and a c-j Premiere 11A. I'm not sure the age of any of the tubes of the c-j, I bought it used and have had it for about 1 1/2 years. Would a tube or tubes going bad manifest in this way. There are no strange noises or anything coming from the left channel, just the slightly lowered gain. Thanks for your help.
