Thanks for the suggestions. So I take it as far as the blurry picture goes, I should start by looking at my signal going from the antenna inputs to the tuner? I know the internal wiring from the inputs to the tuner is right where I was doing a lot of soldering for the filter caps. I wonder if it got damaged. I try some alligator clips across it and see if anything changes, perhaps?

Any thoughts where the "big noise in the signal" might be coming from? Could that be a tuner tube developing an issue? Or maybe a dirty tuner?

I am hearing static audio on the channels with no signal, by the way. I just had it turned down during recording. Beyond the filter hum when I started, I haven't had any audio issues with this.
