That is a nice Stereo Theater. Probably a 1962 model. Thanks for sharing that video, Elton. :D

A caveat I might offer, if I may. One must be careful powering up a TV chassis on a Variac without disabling/pulling the horizonatal output tube. At lower voltages, the horizontal oscillator may not run, possibly red-plating the HOT. And that can be hard on the flyback transformer.

Agreed ... the guy didn't seem to concerned about that did he?... I would at least use a dimbulb setup...

Shango measures cathode current and uses a Kill-A-Watt on the input voltage, along with a dim bulb of varying wattages. Many of us aren't as brave around high voltage as Shango, so we might get by disabling the horizonatal output tube, then powering up on a dim bulb and/or Kill-A-Watt. That will let us check the power supply, then we can fire up the high voltage. The guy who made this video comes across lots of interesting stuff.

shango66 does a lot of iffy stuff I wouldn't try but he seems to get away with it, and he does know his stuff for sure.

I knew from Shang066's early youtube videos, he was in the servicing business from a young age like me :D - but he stuck with it and got good at it unlike myself, now specializing in phonographs, domestic tube and transistor consumer electronics. Shang066 knows exactly how to quickly diagnose issues. I learn from every video and he talks and tri-oscillates all through it exactly like a friend of mine who would ex-terpolate and quadrangulate technical issues during the VCR craze 25-30 years ago. Shango has way more patience than I would for imported electronics as well, hats off to that! ;)

All the "newer" test equipment is reminiscent of Norm Abrams' extensive specialized tools on Yankee workshop. :mrgreen: would not be surprised if he selected those pieces while employed as a "Journeyman" then given them later in lieu of wages. I ended up with my first employer's Oscilloscope, and RCA WO-91b. Good stuff is rarely bought new by Heath-EICO kit builders on a budget :oops: OOPS! I resemble that.

Wonder what Shango does for a living? He is an amazingly talented guy, although a bit on the accentric side. I wish I knew as much as you have forgotten about TV's, though, Dave. ;)
