Electronics engineer / knowledgable hobbyist for help with vintage valve amplifier fault

I have some limited electronics knowledge (and some test equipment inc. a valve tester) but need help with a 1950's valve amplifier fault that's got me beat. Might be helpful if anyone replying had an oscilloscope, signal generator and a variable transformer (?)

Thank you for any responses.

I'll have a look for it later - haven't seen it for a while...

Are you by the old HMV door? I might drop it in one day..
