Hello everyone,
Well, I think I have it. I'm working on a Zenith 7H822 AM/FM radio. I've done the tubes, caps and resistors. When I first turn it on I get a crackling that sounds like lightning on AM only. After a few minutes it goes away. Does it sound like I have it?
If so, how do I determine which IF can has the bad one? I saw a thread on this phorum a while ago that shows how to replace them, but I guess I could just replace the can (I have some spares). I just need a way to locate the bad one.
Thanks.
