Ok now I'm trying to locate a CRT Tester/Rejuvinator with the right adapters. I'm looking at a couple of Sencore CR70. with the CR70 does anyone know what adapter will work for this set? the Picture tube number is 25ZP22

I don't know about the Sencore; but, if you get a B&K 467, 470, 480, or 490, the correct adapter for that tube is CR3.

I found a Sencore CR70 with all adapters on Ebay, most auctions say AS IS deal, and has not been tested other than powering up. Now how reliable are these things?

Hmmm no tubes.

I remember when we started working on these sets with the modules. For a time, we had a load of new modules and could repair the sets in no time at all. After replacing a few, we figured out what was going bad on the OEM modules, and repaired them ourselves. I never had a case where I went to the customers home, popped out the chassis, and replaced the bad module, collected the $$$ and left. Of course, we weren't a Motorola dealer, and these sets were 6-8 years old when I came along.

I'll bet that a new CRT would make this set shine again. Check out the cam switch first.

Fellow tv collector. What is the EIA number on that CRT? IT should above the type number. If it's 836 or 101 forget it. It's automatically bad. Also clean up that crummy looking anode connector to minimize corona leakage.

EIA is 185

my buddy has one of these quasars.it has a nicely made cabinet but came with one of those funky crts.the orange red,etc.he changed it out with a rebuilt sylvania tube and it really looks good.very nice swap and other than the crts,those quasar sets were pretty well made.i think those crts were in some of the lower level cabinets.the mid 70s were good performers with nice sharp crts.good luck on this

The EIA number for Motorola was 185. I remember reading somewhere that Motorola was setting up there own production line for CRT's. Big mistake. They're the only ones that made the 21GFP22, which was also a lousy tube. Just wait for another CRT before proceeding with other repairs. I'll be well worth the wait. Dave.

So your saying a Rejuvinator will not fix this tube?

Also if i do need to locate another Tube, where would i be able to find one?

I'm sure Video Display Corp. will have a sub for this tube; or, I'm sure most any 23V delta gun CRT from the '70's would work (someone please confirm this). If you could find a '70's era Zenith 23" console that was beat up, you could probably use the CRT out of it. Those Zenith tubes seem to hold up the best. I think most '60's and '70's rectangular 25-P22's and the later 23V tubes will interchange as long as they are of the delta gun type and the mounting is correct.

I'm sure a rejuvenator will help your tube; but, the fix will not be permanent. It could last anywhere between a day and a year or more; but, a good CRT is the only "real" fix.

bgadow · #56 10-05-2010, 11:08 PM

Yes, I think that is correct about those 23V tubes being compatible. With a little patience one will turn up, either new/used/rebuilt.

I have a few works-in-a-drawer chassis tucked away. Probably some parts missing, but if somebody is ever looking for something...let me know. Eventually they'll get tossed. (it will be about a week before I find a Quasar myself!)

Here's a picture of the set on after cleaning most of the controls and the picture tube connections

dieseljeep · #58 10-07-2010, 09:27 AM

I was wrong again! Second time this year. The picture looks very respectable. Fine picture for a tube that was never rejuvenated.

tvcollector · #59 10-07-2010, 03:22 PM

In the pictures the tube looks fine, the color is set to where anymore increased color will cause much more bleeding. If you look at the pictures you can see the colors on the screen bleeding a little. Also the full brightness, in the pictures look fine but in person the tube can be a little brighter.. I'm waiting on my Sencore CR70 Rejuvinator i purchased off ebay.. I hope it helps..

tvcollector, I'm wondering if you are anywhere near me. These sets were just being introduced when I got out of school and joined Motorola, and it would be a kick to see one operating in person again.
