Good thought...I did check for that. In fact, I even took a 1/4 wide piece of paper and tediously slid it between the fins with the tuning gang closed and was able to slide it through each side without problem. Usually when the plates are touching, you'll hear an audible click or pop when you tune through the dial and reach that point...this has no discernable leave off point...it's just the normal static. There are 5 different trimmers on the chassis itself, along with the 3 in each of the IF cans, so there are a lot of possible adjustments. The ones for the 540 end of the dial produce no change. I'd think it was a dirty tube socket, but if that was the case I don't think I'd receive any stations.
