15 meg sounds high, are you sure that is the correct part?
Have you cleaned the pins of the tubes in the IF amp?

Yeah, 15 meg: brown, green, blue - see attached pic (yep that solder joint is factory) and schematic. How critical do you think that value is? If I put say two 2.2's in series would that be sufficient? It's not like there's going to be any useful amount of current through a 15M, it's just to complete the circuit but not actually really do anything right?
I've swapped around the IF tubes several times and wiggled them and doesn't affect the noise. I wiggled all of the tubes too and even tapping on the chassis does nothing so really doesn't seem like something loose. Going to hit an electronics store on the way home and if I have to stick six 2.2M's together I will, lol!
