Speaking of which...


I was a dumbass and decided to twiddle around with the IF alignment, since I wasn't passing a video or audio signal at all. Should have done some voltage measurements first, damn tuner wasn't getting any B+! The alignment wasn't far off thankfully, I only had to tweak a few transformers to get it looking respectable. But I followed the loss of power back to it's cause, which ended up being the field neutralization pot on the LV cage.



This isn't a normal pot though, it's tapped in the center. Anyone have a spare they could donate to the cause, or know of one that's available on the open market? I suppose this would explain the excessive B+ voltages as well, since half the chassis wasn't being powered.
