The g1 capacitor is a good start too.
I would go thru all the wax capacitors one at a time as they all get a bit leaky.
Some of the resistors may have drifted in value too. You can measure them with the resistance range on a modern meter.
I shot of switch cleaner on the wave change control will also go some way to getting rid of crackles.
Thank you for such prompt advice. I have downloaded the service sheet and circuit diagram and will try to understand it. I will go through the various things and get hold of the switch cleaner to see if that helps. The g1 capacitor on my diagram is designated 'C40' and is .005 microfarads @ 1000V.m I'll get one and replace the one inside the P35. (I'm way over my head here but I will not give up yet)
