This set is fascinating to me. I spent a good bit of time looking over my Motorola service book on the TS-4's the last few days and no pictures of the .03 caps on top of the board are shown or mentioned.
Also, unless I missed someting, no .03 mfd's are listed in the sweep circuits. One variation does show a .0005 horizontal coupling. The high voltage cage is pictured correctly as well as no fine tuning. All of my TS-4's have fine tuning. Keep us informed. I want to see this one play! |
Mine is a cross between the TS-4 early and late found in Riders Vol #1. You can download a scan from the Early Television Foundation.
I wonder if those 0.03 caps could still be good ? I think they're oil filled and those tend to last a long time. I also really want to retain the original look and they don't look easy to rebuild. If I do need to replace them, I'd like to get some nice ASC caps like I used in my Hallicrafters. They are 0.022 mfd @ 6,000v caps from Allied Electronics. Not quite 0.03 but they worked fine. Sadly, they're out of stock of just about all ASC HV caps :( http://farm5.static.flickr.com/4060/...c643bfcf2b.jpg |
I'm just about done with the cabinet. One of the last tasks was to apply the decals.
These were fairly easy. http://farm7.static.flickr.com/6021/...97ff0a6ce3.jpg Now for the tricky part - cutting them up for the channel #1 lineup. http://farm7.static.flickr.com/6016/...38d229807b.jpg http://farm7.static.flickr.com/6005/...fd45fedae4.jpg Here they after a few coats of lacquer. The 7 and 5-6 are slight askew, but I doubt most folks will notice. http://farm7.static.flickr.com/6134/...bf1d5ef5e1.jpg |
Looks good Bob as usual. I have 5 of these little guys. So far, I have only restored one of them. Don't remember the version but it doesn't have channel 1. Another one that I have is a blonde cabinet. Still sitting in queue. And another one has channel 1 but one of the coils below was physically damaged. I have an 8" Motorola, can't remember the number that may well become a donor chassis. The CRT tests excellent as well. All in all, most of my 7JP4 tubes are adequate with two rather weak but not dead.
I especially like the decals that you came up with! |
Time to tackle the old, melted CRT mask. Most of it peeled away. I then used water and a small brush to work the rest loose.
Yummy :yuck: http://farm7.static.flickr.com/6071/...5116209d_z.jpg http://farm7.static.flickr.com/6088/...7251069b_z.jpg Here's the new reproduction mask installed. http://farm7.static.flickr.com/6081/...a511df12_z.jpg The original brown paint had mostly flaked off the bottom. I recently read a tip that the Rustoleum "camouflage" series works well for cabinet bottoms, backs and insides. First, I removed the feet and masked off the cabinet and label. Then, sealed it with shellac and sprayed on a couple light coats. It's very flat and I think looks pretty good. http://farm7.static.flickr.com/6183/...2d72ef1d_z.jpg http://farm7.static.flickr.com/6185/...3f0bd590_z.jpg The rest of the cabinet is just about done too. I think one more round of 1000 grit sanding and a final coat of semi-gloss lacquer will do it. What I did was patch the veneer chips and lightly sand the top layer of the old finish. Then fill in the voids with lacquer sanding sealer. Finally, put on a few coast of semi-gloss lacquer. My goal was to retain the original patina, but fix up the biggest flaws and protect it. http://farm7.static.flickr.com/6190/...2e8bd922_z.jpg http://farm7.static.flickr.com/6084/...9db10ef8_z.jpg http://farm7.static.flickr.com/6079/...dce4b223_z.jpg If you're wondering why the remote controls to the right are upside down - it's so they don't scratch my vintage coffee table :) |

True, but I do have a towel under it :) Plus I'm not really doing much work on it in this room - it's just a good area to take photos.
Those plastic remotes banging down on the table again and again and sliding around are really rough on the lacquer finish. |
Ask me how I know you're never gonna have kids, Bob. :D

Looks great. I have used water to get that nasty old gasket off too. I found that info a few years ago either here or on ARF. You have more tenacity than I. As as to the remotes, I do the same thing whilst they are sitting on the bed so that the buttons do not get pushed by the cats... |

I'd love to know what within us makes us appreciate these old sets. I'm the only person I know in my day to day life that prefers and enjoys my '49 Motorola over an LG 52" HD TV. |

If someone were to offer up a rare TV for the show, can we be assured that a vintage electronics expert would be on hand to guide the project? With all due respect, and I am a fan of the show; I was a bit disappointed in the restoration of the Thunderbolt Air Raid Siren. I collect and restore air raid sirens as well as vintage TVs and radios, and although the physical restoration of the sheet metal was excellent, the siren was incomplete (missing the entire Roots blower, motor and housing, and the RCM cabinet and controls), and this was not explained in the show. I understand that the watching public might not be aware nor care of those details, but I would venture to guess that most owners of vintage TV sets would want to be assured that if you took on a project like a TV, that you would be sure to keep correctness and completeness as priorities.

Wait a minute: How'd my reply go in the wrong thread?

I dunno! Anyway, why do I have 5 of these sets? Well, I remember one being in basement when I was a kid. Dad worked on sets and I just remembered how cute it was! Fast forward, One of the ones that I have is now restored and works well. I still have 4 in queue. One is a blonde cabinet and one has channel 1. So, I guess I am like the rest of us that just wants these little guys... http://www.antiqueradios.com/forums/...p?f=3&t=144209 |

Sandy G,
If I recall correctly, the first TV station you could easily receive was WBTV in Charlotte, NC. Which signed on before the debut of WJHL-TV in 1953. The difficulty of reception and the expense of the early TV sets limited their acceptance when the VT 71 was first built. |
I was rearranging my VT71s and took the opportunity to snap some photos of all three side by side. The blonde is a work in progress and it's logo and CRT have been removed.
Left-to-right: Very early version with walnut cabinet, mahogany and blonde http://farm9.staticflickr.com/8533/8...c3a75494_b.jpg http://farm9.staticflickr.com/8137/8...9b89d2b5_b.jpg |
Bob-
Here are my serial numbers and dates of my two VT-71s. The older one is not marked TS-4D after all. Walnut #5782 January 30, 1948 Steel chassis Blond TS-4D #24874 March 30, 1948 Copper chassis On both of mine, the bottom control with the metal cap is called "audio adjust". I am going to start restoring the walnut one now. It does have the round discs on the lower sides near the front. (I thought it was mahogany until I looked at your three pictures. I am very poor at recognizing wood types.) I had bought a restored VT-71 cabinet on Ebay a number of years ago, and it is definitely mahogany, comparing to your three sets. Now, I guess I have an excuse to find a third one of these (one of each finish). |
My walnut set's cabinet shows the 7F8 tube, but the chassis itself does not have one, it appears, but rather a miniature tube (another 6AG5?).
I am going to restore the blond TS-4D now instead, I decided. Its cabinet is in very nice condition with good decals, so maybe its CRT will be strong if I am lucky. Around 1980, I had it partially working, but that was before I knew I needed to replace every paper capacitor. I remember that I put 6000V disc capacitors in it; those will be replaced again with some ASCs that I already bought. |
That should be a 12AT7 tube. Should like you might have a mismatched cabinet and chassis.
I'm curious to see of photo of that walnut cabinet. I've only seen two ever in walnut - mine and the TS-4B on ebay. Neither have the side plugs. |
I will take pictures of it, along with my mahogany empty cabinet, and post them in the next few days.
