Update - just wanted to report that ALL IS WELL once again...the loss of right gain is NO LONGER. It might have been a "newbee" problem. I've only had 1.5 year of experience with my tube amp (first tube gear). Upto now I've only been resetting the bias but not the "offset". The owners manual (4 photocopied pages in all) does not discuss bias or offset at all - very odd. Must be a language problem, the amp is made in Italy or I did not receive all documents from the dealer. All I can say is, after resetting the bias and the offset, the sound appears to be completely in balanced. I'm a happy camper! Best of luck to you all...
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.
