Realistic SAF-40D Right Channel Problem

[artsybob]

My Realistic SAF-40D tube integrated amp was working flawlessly for the three years since I had it recapped. However, my right channel speaker cut out a few weeks ago. No sound will come out of it though both channels come in clearly through my headphones. I thought it might have been the speaker caps going bad, so I replaced them but that didn't help. Could it be the right-side speaker terminal has gone bad? Has anyone else had a problem like this with their tube amp? Thanks

does this have a phase reverse switch? No idea what the particulars are on this but most amps run the headphone from the output of the power amp. If the cans work on both channels, I'm inclined to think the amp is basically fine, but there is something between the output transformer and the speaker terminal. Usually thats a speaker selector, impedance selector, or phase reverse switch. Might be able to bobble the switch and get it to come back. If that does it, clean the switch.

Thanks @gadget73 ! I toggled the headphones-to-speaker and the phase reverse switches and that seems to have done the trick! I'll go and spray the controls with some contact cleaner. I need to spray the volume knob too since that has been getting a little scratchy
