Zenith 7H822Z troubles

[Jonathan]

Thanks Chad,

I think you might just be right. It doesn't really crackle at all, and AC is getting in from somewhere, so it has to be a weak tube. The 35B5 I replaced with a known good one just for kicks, and the 19T8 seems fine, and I just replaced the 12AU6 since it had a burnt out filament when I got it. Either the IF tubes or the RF tubes. I'm going to test for shorts, AC has to be leaking in from somewhere.

Thanks.

Jonathan
