I really like RCA's "V" shaped emblem with the color shield below.

Not like that pilot who tried flying a B52 sideways one time, only a few hundred feet up in the air... http://en.wikipedia.org/wiki/1994_Fa...ase_B-52_crash
![]() Good thing Phil got that TV, I'm in Seattle too, but I can't physically handle a set that big.

I haven't done anything to the cabinet except for a quick wipe with a soft cloth & mineral spirits to remove old furniture polish & dust. It has little nicks and scuffs if you look closely, but it should look great after a standard touch-up. The finish has a very deep appearance -- more than the usual number of lacquer coats, perhaps. It's a quality cabinet. The side panels have veneer but the rest looks like solid wood.
This set was well cared for. This seller got it from the original family in Tacoma. I think he paid only a few bucks or got it free. He buys various things from estates and remarked on how old TVs are sometimes giveaway items. I gave him my email address and told him what to watch for in these lines. In the cabinet I found an RCA service tag from 1977 with the owner's name & address. No work is recorded, so perhaps they made another tag or the owners decided not to fix it after they got a price estimate. Replacing the fuse holder sounds like a fine idea. Seems odd that a serviceman would remove a fuse and not replace it. Perhaps some fumblefingers owner removed it and dropped it into the gap between the chassis and the cabinet side, where you can't retrieve it without pulling the chassis. Despite all my lectures to self, I did try powering it up after checking & cleaning all the tubes. Tubes lit up, but there was no sign of B+. It drew much less current than you'd expect, and there was no spooling-up sound from the HV or static from the speakers. I found one fuse on the top of the chassis (what you'd call the top when it's lying flat). Eventually I spotted this fuse on a Sams diagram. My CTC-11 chassis are very similar to this, but they don't have a fuse in that spot. I see a part labeled Thermal Switch in the schematic. I guess it's a B+ delay similar the one in some old DuMonts. Several seconds after powering up, you can hear it click on. I'm curious to see what it looks like in the flesh. The drawing in the schematic reminds me of a toaster switch: power resistor plus bimetallic strip, perhaps. It's dumb luck that I got this set. I happened to check CL a few minutes after he posted the ad, and I phoned him immediately. Half an hour after he had put up the ad, I was tooling down the highway with cash in hand. Perhaps getting a good deal once in a blue moon will help balance all the other times I've paid more than I should ![]() Phil Nelson |

probably from common sense, we're moving later this year and hauling around 3 heavy TV's is not in my future considering my back problems.

Hey Nick! I hate to see anyone having back troubles that young. Mine has been giving me grief since around Thanksgiving. I go for an MRI Wed. A.M. Nothing seemed to work regarding Medication or therapy.

I think the gray-faced crt is correct for these. 21AXP22/21CYP22 were that way? The 21FBP22, etc, were greenish.
Nice,nice set.

If it's a 7, it will have a CYP.

That missing fuse is in on the B+ line. My 10C has the same fuse set-up. I've never gotten bitten by it in all these years.
Fine looking set, there. I cant wait to see it working! |

I guess the CRT is a 21CYP22, although I can't see any marks besides a serial number. Using 21CYP22 settings when testing it on my CR70 gave sensible results.
I made a makeshift fuse cap and the B+ lit up, but I didn't give it much voltage, and only did a very brief trial to confirm that there are signs of life. This set will have to wait its turn. When the time comes, I'll replace the p-s electrolytics before powering it up again. Phil Nelson |

Definitely some life in this old clunker.
![]() So far, all I've done is to replace the electrolytics and some small caps on the sweep boards. Haven't had time yet to do any of the usual setup, or even adjust the focus. The audio from this set is stunning. Television for grownups. Phil Nelson http://antiqueradio.org/index.html |

Well, back when you paid quite a bit for a TV, you got quality. very well built IMO.
You can keep your "picture frame TVs from CHINA" |

I know, trust me. I'm very abusive to my body, I assume I'll slide into the grave in a back brace doped up on vicodin at that pace I'm currently on. A big part of it is the bed I'm sleeping in- it's a Simmons pillowtop that caved in on itself. They refused to honor the warranty, so I know have to take them to court. That's a story for another day though, if you want to know more about it, just look at the customer opinions of Simmons and their matresses....
