Another one time find LOOK!

[drh4683]

estate sale sunday was a total sucess! I was fortunate enough to come across a "SANFORD" model 21-DC-8775 rca CTC-7! It was priced at $20. The set was still in the living room in the original Downers Grove home! This set is in great shape yet, still has all of its original knobs and name plates! I quickly wanted to see the back for a model number but the back was gone. I was so po'd, my excitement level dropped as part of the TV was gone. I looked all over the house thinking the back had to be someplace. After about 10 min. of searching, I found it behind the workbench in the basement, still intact!!!!!!!!! I couldnt believe it, that was more luck than finding the tv itself!
As I brought the back upstairs to fit it on the set, I checked out to see some date codes and if most original tubes were in there. Looked pretty nice in there, most original tubes, but many were missing (about 7) so I figured this set has some issues and will probably take alot of effort to bring it back to life. Other than missing tubes, it looked like nobody tinkered with it, all original hardware still holding the chassis in place etc. The home was completely run down and very cluttered, so I know this tv was basically "hidden" in the living room for many years with its back off. Still has its original CRT dated 58-04. Most date codes are 58-04.
The only reason I think this set survived is because the man was single. Most bachelor estate sales have all old stuff, even tvs and the home is always run down and abused over grown bushes covering half the house etc. He was a ham operator and a koren war vet. Tons of radio and tube equipment scattered all over the place.

picture shot!

YES, all I did was replace the missing tubes and powered it up with the variac, and this is what I got! Im still shocked I get a color picture! I didnt touch a single control! CRT tested weak, so I will need to zap it.
the one filter lytic got burning hot, so the tv got shut down quick! I will recap the entire set to make it a reliable peice!

(what you see is a vhs recording of 9-11 news)

That is a beautiful set . the tubes for that set should not be hard to find.
what is the picture tube #. 21cyp22?

OMIGAWD !!!<Whimper, whimper, whimper...>-Sandy G. At least one of US found it & it didn't get to go to Der Landfill...<Grin>

[drh4683]

pulled the chassis on it. A total of 56 capacitors, and a total of 56 that need to be replaced! Once the caps are replaced, this should be as reliable as any other tv. Wax caps are all over this set, and they made a mess!
Yes, 21CYP22 crt.

Wow, what a find!
You might try cooking the CRT at 8 volts for awhile to see if it will recover.

Doug,

Kewl find! I think this might be the first time I've seen this model (other than RCA advertisments). Seems a trend is starting for finding rare sets that actually play when they get home!

[Chad Hauris]

Doug, that crt looks good, I would not mess with it. Looks like red, green, and blue are there...you could touch up the screen controls to check balance. I only do the boosted heater voltage trick on the crt when it's really bad visually, because I do think it shortens overall CRT life.

[nasadowsk]

Can you get CYP22s rebuilt? IIRC, they're basically the same as later tubes...

[Charlie]

IMS, Video Display Corp in Dallas will do a 21CYP. He will also do the 19" roundie being that the guns are all basically the same. The only round color tubes he wont touch are the metal/glass jugs.

I agree with Chad. Don't mess with the CRT as it is still looks very healthy. Personally, I wouldn't raise the heater voltage. Just let the heaters do what they were made for at the designed voltage. I would try for 2 weeks straight. Don't try to shock it with anything and it will be just fine. Attaboy!
