Hi Guys,

I've noticed that when I change channels from my Lead to Rhythm on my Mark III greenstripe the gain on the lead channel decreases when I go back to it. It's not as full and sounds thinner. Also, when I switch from the lead to the r1 or r2 channels there a second or so of loud, static-y noise. Any thoughts about what might be going on?

Thanks guys!
 
Sounds like something is wrong with the optocouplers for the channel switching. If you are not familiar with tube amp circuits best take it to a qualified tech.
 
Thanks for the reply. I’ve never even heard of these things so I have to find a good tube amp repair
