Any Zenith experts around Los Angeles?

All those things were tested a couple of years ago when I first got this set. It's all, pretty much, documented in previous threads. Tested the voltages at the socket, etc. All were in spec when tested back then.

There's ringing in a circuit and that's what I'm looking for with the jailbars. I'm pretty sure the problem with the setup circuit is a resistor. I have the replacements and will be working on replacing them.

Thanks
