Default Re: KT88 construction problem

Another problem!

I connected up the amplifier to loudspeakers and switched on with high hopes. However although the left channel sounded good, the right channel was completely dead. I tried different sources and also swapping the speakers around but it is the amplifier and even with the volume control turned up full there is no sound at all from the right hand speaker. (There is slight hum and hiss from the left, as would be expected.) I reopened the amplifier and checked all resistances and voltages - perfect on both channels.

I have checked the output wiring and as far as I can see it is all OK.

Any suggestions?
