Bad tuner

[DaveWM]

ok pretty sure the tuner is bad in my zenith console PN 175-589 zenith.

I say this since tube swap does not help, IF feed to tv results in perfect pic.

the balun is burned up (open and one side looks cooked). My guess is lightning strike.

Anyway anyone have any luck fixing a tuner? What am I looking for?

Is there a way to either replace or bypass the balun, assuming that is the only problem.

I get a snowy interference laden pic.

I could of course just bypass the tuner completely and put in a RCA connector for a composite video, but I like to have things that work.

Seems like such a waste to have all those un used tubes...
