Old Muntz TV for sale Locally to me, Should I pick it up?

OK So here's a YouTube Link to my Video showing what the TV is currently doing.

Hopefully this will work better, and won't require you to log into a Google Account.

P. S. You'll have to turn up the volume really loud to hear the audio.

I'm not sure what I'm suppose to be hearing in that video?

Say... what ever happened you measuring those voltages I asked about per Sams voltage chart on the pins of the 6V6 audio output tube? When I asked you a couple pages back, you said you hadn't yet, but were instead going to replace every resistor because they were all bad? Those voltage measurements in that stage could be crucial to figuring out why R62 is overheating and the cause of your excess current draw. That circuit derives it's supply directly from the focus control through R62 and the voltages developed are provided to the entire audio circuit. I'm getting the impression that you prefer avoiding any troubleshooting, but would rather replace every component in sight. Eventually you're going to run out of components to replace, and then what?

Well I'm hearing what sounds like vertical or horizontal oscillation going on, but I'm not sure if that's what I'm hearing or not, it's a kind of medium pitched rapid snapping noise, very similar to a taser going off.
I need confirmation as to whether or not that's the vertical, horizontal or high voltage running.

As for the voltages on the 6V6, I got side tracked, I have ADHD, so I get side tracked easily.
I'll get right to measuring those voltages.

OK, I'll be looking forward to those voltage measurements. My next question is do you have a high voltage probe? If not a probe how about a compact florescent bulb? You need something to indicate the presence of high voltage. Once you know you have HV, my next concern would be adjusting the ion trap. The ion trap has to be set properly or you'll never see a raster.

Ok, so pin 3 of the 6V6 tube is giving a funky reading, it's giving a reading of -0.195vdc which doesn't seem right...
And that reading was taken in reference to pin 8 of the 6V6 tube just like the manual said.

And no, I don't have a high voltage probe.
I do have some CFLs but they're all burned out or broken unfortunately.

What did pin 4 measure? If you have dc voltage on pin 4(screen) and nothing on 3(plate)I'd suspect the primary of your output transformer could be shorting to ground. You could also try measuring those two pins in respect to chassis ground. Any voltage readings on those two pins will indicate if there's a short in that transformer primary.

Actually the output tranny is attached to the speaker and the speaker unplugs from the chassis, and it's currently not connected to the TV, would not having the speaker in circuit mess things up?

[Kevin Kuehn]

Another thought... pull the 6V6 and see if the voltage on pin 3 changes, either referenced from pin 8 or ground.

Pin 4 is spot on voltage wise on the 6V6 tube, and pin 3 once I connected the speaker was giving me a +25 vdc and dropping. So not sure what's going on with that.
