Confusing new "RCA"

[maxhifi]

I was watching the tv last night - am sure the picture tube is weak, it goes totally dark when brightness is down and loses focus when it's set too high. Contrast is also pretty unremarkable. Still, it does a good enough job of playing the evening news and keeping the hours off my ctc-38 (my REAL RCA)

Linearity is also kind of touchy and seems to vary a bit with line voltage - kind of like my similar era 19 inch admiral. The sound is also a little bad, it's got buzz leaking through from the video signal and it's also got a bit of distortion. I am thinking that this TV is not going to get a full re-build, it just doesn't seem worth it to me... I'd rather put effort into a real RCA, or even a GE
