I kind of figured that, so I bought a Zenith roundie recently in working condition, semi-restored. Worked for about two minutes when I got it home, picture started to shrink from the bottom, and I started to smell something. Shut it down. What a let down. I'll get to that once I get the customer work done.
RCAs, though, I have zero luck with.
I guess you can call this thread a "rant". Your support and commiseration is appreciated
