I replaced the wacky IF trimmer with an exact replacement from a 70 chassis which was also marked yellow but I have still have the exact problem... no volume control and lots of static unless I put my finger over the trimmer grounding it to the chassis with my hand which then brings it back sounding perfectly and restores volume control. Also any attempt to calibrate the oscillator or other trimmers just results in static and no improvement unless I make the adjustment while I'm grounding IF trimmer. one other thing to note my volume adjuster has a couple of dead spots in it where it binds so that needs to be replaced as well there's no chance that is related is there?
