I've noticed on my Mark V head that I have less volume on channel 1. Normally I have all my channel volumes about 9 to 10 o'clock ish, about quarter of a way up. Channel 1 used to be very loud at 9 o'clock, that I had to turn it down lower than channels 2 and 3. Now I need to keep my channel 1 volume about noon and even then it's barely louder than channels 2 and 3. I've also noticed a considerable lack of gain and saturation from channels 2 and 3. Channel 3 on Mark iv mode's gain almost sounds like a jcm800 gain wise and thats with the gain nearly maxed on channel 3.
I've looked at the power tubes in the back. The 4 6L6s' are glowing normally. I also saw the 5U4G tube does not have a glow on top as compared to the 6L6 tubes. Is this normal?
Anything else I should check?
