Arrow 1972 Sharp 2U-121C B&W Vacuum Tube TV

Picked up this Rare 1972 Sharp 2U-121C Black and White Vacuum Tube TV for free, untested. Gave it a cleaning, polishing. It is in real nice condition, no cracks or faults on the case.Turned it on waited 45 seconds and it works. I believe this was made in 1971-72 ?? Made in Japan.
I cant find any info on it. I peeked inside and noticed it is a tube hybrid set ?

Some pics and video here: http://www.youtube.com/watch?v=R_h7g...m-upload_owner

Hi!

I would take the back off, remove the metal clip holding on the power cord, and turn on the tv and look to be sure all the tubes light up, I assume its a series string, so if one comes on they all should, but its a simple thing not to overlook...... See if you can feel any static on the front of the screen when you turn it on and off... If you can't tell, try testing for HV with a neon light. Get one, tie it to a wood stick and move it near the hv lead to the picture tube, if it don't light when the tv is on, you may have something wrong with the horiz, or hv rectifier.... Be sure none of the tubes have hot glowing red plates, like around the horiz output, that could be an oscillator not working...... Turn it on in a not too lit up room so you can see the plates...

Well, I'm an idiot !
I turned it on again after dinner, and waited roughly 45 seconds (longer than usual), and what do you know, I got a picture.
Here's a video of it.

Sams lists a 2U-121S about 71-72
Would guess the C is for Canada.
I remember them but all tube or hybrid? Been too long.

I'm surprised there is no CSA approval sticker on it.
Canada seemed to be pretty strict with that.

The heat of the tubes probably dried off the glue and it peeled off.

That's another set that was reasonably clean to begin with.
Grungy sets, no matter how hard you work cleaning them, don't come back that nice. Especially the lousy cigarette crud, plus the odor!

If the set doesnt look like it'll clean up well, or has sign of smoke, I just leave it !
Not worth getting it. I only pickup cosmetically 'clean' small sets !
