Hi Roy,

I don't think you will do much harm to the 6Q7 heating the grid cap other than the glue coming loose. If you have solder wick, a solder sucker, etc., you can try to remove all solder, clean the cap and wire as best you can and resolder it. Yeah, I would not worry about anything other than the OF tube plate fluctuation. If you do not get noise with the grid wire off the 6Q7 but DO get noise with it connected, I think that the issue is before the grid cap. I AM worried about the amount of plate fluctuation on that 6K7. If you don't see the same fluctuation at the B+ point closes to the 2nd IF transformer primary (cut off some insulation and connect to it), then the problem is in the 2nd IF transformer primary. Disassemble the transformer and check the connections. If you do see fluctuations at the B+ connection to the 2nd IF transformer primary.

Good luck with this problem. I'm sure that you will nail it.
