Turn channels. You should get strong static crashes between

in the IF. DO NOT TWEAK IF COILS ! Even if it fixed it
you would be just covering up a failed component. Its not
normal drift that much.
If you get the good snow and strong crashes look to the tuner
tubes next. Do not trust a tube checker. Sub in known good
tubes of a brand name. If you dont need tubes in the end all
the tubes are common. 6HA5 used in Zenith from abt 1960 to
the end. 6BZ6, 6EH7, 6EJ7 all used in Zenith and many others.
Start with that.......

Yeah. Before I started messing with it, once the image went blank, I got no static on the screen, and no sound. No crashes between changing of channels, Even when I turn the AGC to bring snow back to the screen, the sound is soft and weak.

Both sets are like this.
