Re: Tandberg Huldra 8 valve failure
It would seem that the EF89 is NOT at fault but the OP cannot give us the voltage readings. It is a red herring that the filament glow is not as bright as the other valves, but the valve is warming.
I think someone needs to move the OP on into actually finding the fault which will probably be in the audio circuit. At present we seem to be chasing smoke.
