Using brighteners?

[refill233]

I first used the Beltron in early 1970's. It was the quick and easy picture tube fix. We charged $20.00 for Color and $10.00 for B&W. Also we gave 1yr. on the tube. That was your money refunded on the purchase of a new or rebuilt tube. Most lasted the year. It has brought tubes back that others wouldn't touch. The 8080A's were the super restorers.
They took a somewhat softer approach on the tube. They changed the polarity on the capacitors which was easier on the tube with the same good results.

Looking up for the Beltrons. Check this one out on Ebay.

Nobody bought it. It's a 2972E just like mine. Notice the big universal adaptor with a glom of sockets on one end.

50 bucks is the going rate. His opener of $99 was too high. If he relists it for no reserve and 25 bucks, it will be worth keeping an eye on...

Well I picked up a 8080a recently. Or it could be a 8081 according to a paper I found in the case. Allegedly it was updated. Well I was missing a couple key adapters so thanks to this post I may have it figured out. I have two setup books...one old one that refers to sockets instead of BR adapters. I also got a slew of oddball papers some certificates to give out, stickers, and even some ad's for newspapers. A few spare bulbs were in there too. Do they burn out often?
I decided to use some crt pigtails I had on a elcheapo tube tester. I will be making one for B/W A BR-3/BR-4 combo into a octal plug. And a BR-1/BR-2 into an octal. I have it all figured out amazingly except I noticed on my B/W pigtail it has crt pin 10 included. I should just do away with that one correct? Why do you think the cheapo tester included it?
Hopefully when I get a scanner going I can scan some of the papers I got with the unit to share.

I have two sets of instructions. I'm not sure which one is newer. One says"Heater meter will read approximately 14 volts until picture tube is engaged)" the other says "AC voltage meter will read approximately 15V until the picture tube is engaged." These quotes are both from the beginning paragraphs. Oh, my machine is a 8080a. I found a picture of a 8081 and this is not one.

I noticed my short light is on even though I do not have a crt hooked up. What would cause this?

[newhallone]

Aha! One set of instructions say if the light comes on there is a short. The other says if it goes out there is a short. So I guess I have to use the one with the light on before connecting the cable. this is also the one that says 15 V. It also has a half sheet of paper with big red letters "IMPORTANT INSTUCTIONS" with "please read and follow closely to get best results from your beltron." in black. This set of instructions say nothing of model number.

The other set that say 14 volt and light comes on when shorted has the title "Beltron picture tube restorer instructions for model 8080a."

When letting a crt "cook" at a higher heater voltage for awhile shouldn't the grid be disconnected somehow? Or doesn't that matter? If I should is there a place I can put a switch in that's preferable?

Well, I'm pretty stoked! I had my first success with my beltron. I tried it out on my 17lp4 for my old Zenith and the emissions were not that great. When it slowly came up it was around .90. So I tried the cleaning function. It all went as the instructions described. I went back to the test and as soon as I had 6.3 volts ...zoom up it went and was very close to 1. And when interrupted it held for a significant amount of time. So I am happy! The beltron works as it's supposed to (at least the test and cleaning functions) and my crt is good.
