Before anyone ask's, This set has been restored!...before I bought it.
Anyway's I've been using this little thing semi-regularily. Good little desk tv.

It has developed an issue with squeeling when the volume is set above half. Just out of knowwhere it will do it, and freak ya out. Especially if ya don't know about the problem. It's intermittant and not heat related. It will do it at start up and after being on for 2 hour's or so. The audio quality will also take a dip whenever it squeels.
I'm not sure if it's just the audio output tube/audioamp/soundif(6U8) or an actual component that's bad, and I don't want to open it up until I get a general idea of what it is. This set's not like other's where I can just take the back off. I gotta take the whole damn thing apart... I'd just test the tube if it were easier to do so, but im a little lazy and want to hear what you all would think off hand.
