Hello, new to forum with a '71-72 150 head. Channel 1 is fine channel 2 has little volume. Am getting input from guitar just not getting amplified. Been doing "tube" stuff so this is a little new. Suggestions of what could be wrong would be appreciated.
Thanks

Well low and behold after reading post on here about loose plugs on circuit boards I decided to check that. Took it off and look over thoroughly and plugged back in. Turned on power and channel 2 was alive. If this happens again I may go ahead and solder the wires direct. Hope this can help someone else.
