Default a question about an icon stereo 20 push pull valve amp

hope you can assist and maybe make some suggestions

My friend has an Icon stereo 20 push pull, no signal from the right hand channel, he has a valve head amp hooked up to it and it seem to be working fine on both channels, any suggestions as to the likely problem!

Start by swapping the valves over to the other channel and see what that does.

No worries, I wouldn't call myself a professional! It could be a lot of things, but swapping valves between channels is the first port of call.

Do you know if this amp. is fixed, or auto. bias, rivendell, if it is the fixed bias do not change the valves because it will need adjustment and you may do damage if it is not adjusted, do you have the instruction manual, this will tell you. BOB

Don't complicate the issue Bob, quickly swapping the valves over to see if it is valves is fine. Once the problem has been semi solved then decide what to do about the bias if necessary
