Do you have the schematic? The Trader index says it's 958 but that seems to be for the P19. The sets may be very similar but I don't know.
Repalce the output stage grid coupler capacitor ( I think that's what Refugee is calling the g1 cap) as a matter of urgency. It may save the output valve and transformer from a nasty fate. It's 0.005uF according to trader 958. A modern 4n7 (4700pF, 0..047uF) plastic cap rated at 250V or more is ideal. Most of us would use 400V or 630V parts simply to save keeping multiple voltage ratings to hand.
Refugee's other advice is all good. Use switch cleaner such as Servisol. Don't use WD40.
Thank you for your advice and the welcome. I will get hold of the condenser and some servisol and see where I get to after that. This is quite a learning curve for me!!!
