Hallicrafters T-54 and Friend
 

Fully functional T-54 and SX-62A

Most recent score
 

This little one I scored this weekend, in trip to a small town near me. It belonged to a guy who was a TV technician in the old days. He is also my wife's uncle. I paid US$ 10,00 for it. It's a Semp ( a brazilian brand ) from around 1967/68/69. He said it worked last time he plugged it. Right now the cord is separated from the TV, but I will test it later. The TV was in a room he has that is full of old stuff ( the old fan seem in one of the photos came from there also ). Sadly, he said that he had more old sets that went to dump recently. The one I saved was the last.

"Hope I haven't confused you too much, but basically you had the right idea"
It makes sense to me now that I know the space between the lines does actually increase. Thanks for the info.
Here's some pictures of a Zenith I've been working on, I got it working, it just needs some work done to the cabinet before I put it back together.

I kind of started this whole vertical size thing with the portholes. In the meantime I realized that the RCA TC-127 that I recently restored has a WIDTH selection switch. Kind of strange I think, but I'm glad its there. I had a bit of shrinkage on one side and that switch took care of it.

Regarding the 1B3 filament winding, the number of turns required to get the 1.4V needed by the tube filament depends on the design of the other windings of the flyback transformer. A specification called the Turns Per Volt Ratio is determined by the ratio of the number of turns in the primary winding to the AC voltage applied across the primary winding. Voltages induced in each secondary will be determined as a function of the Turns Per Volt Ratio. A transformer with a TPV of less than 1 is not uncommon, so a 1/2 turn secondary winding producing 1.4V is not unusual. Many color sets had low-ratio flyback transformers and produced 3.3V for the HV rectifier tube filament (3A3, 3B2, 3AT2, etc.) with single or 1-1/2 turn secondaries while deriving focus rectifier filament voltage for a 1X2, 1V2 or 2AV2 from a 1/2 or 3/4 turn winding.

Hello,

On the web I have found an old German advert for Graetz radio and television sets from the 1950's.

Hi Eckhard,

I couldn't open the movie...the space where it should appear remains "blank" in my computer.

Meanwhile, as I have shown my Semp TV set from the late 60's here comes an older model: a newspaper ad from January, 25, 1954 with the new 17 inch model from Semp.

Hi Captain Video,

try it with this link:

It is a Quicktime video.

German ad
 

Very cool. Nice TV sets they made...is this factory still in operation?

I will have to show this ad to my wife. She has German ancestors, and she actually speaks German. The only German word that I really learned so far is "schnapps" .:D

Garod TV/radio combo
 

Hello There.
I just joined this Forum and i'm looking forward to talking about our old sets.
I own a few.
I have a Motorola VT71 and 3 50's vintage RCA B&W sets and an RCA CTC5 color set.
Also I have the Garod mentioned above which I have mostly working but TV sound is weak but I need to find a knob set for it.
I'd like to add a pic of it but there seems to be a problem with scripts on this page.

Hi. Usually if the pics won't load it's because they're larger than 195 Kb or 900x900, if you shrink them down it might work.

Third 721TS and in-progress Fada 799
 

Here's my third RCA 721TS to date. First one, I sold on eBay after recapping and aligning. Held on to the second one and plan on holding on to this third one a while. This one has an electrodynamic speaker as every other 721TS that I've seen, but has a PM ion trap. I haven't recapped it yet, but have installed the safety devices and re-formed the electrolytics. Shown here is a flash photo of the set displaying a test pattern and another without flash.

Next two pics are of my Fada 799. The first is just the cabinet on display while the chassis is partially disassembled and waiting on a shelf for its repaired tuner to be reinstalled and recapping. Last pic is the set on display before disassembly.

Any tips on photographing sets with non-aluminized CRT so the flash won't wash out the picture and / or cabinet shows up well without flash?

Welcome to AK, Anders ! Nice t'have ya here !! quite a few of us who share the peculiar affliction for ratty-and otherwise-old TV sets...<grin>

Boy sure do enjoy those pics!!

Some of my Italian-made B/W tube sets

1) 1963 Philips, made by Philips' Italian plant, this set uses a 23" CRT with a contoured bonded lens and a transformerless audio output, with high impedance speakers hooked directly to the output tube's plate circuit.

Seems that European CRTs with bonded lenses don't suffer from PVA deterioration and cataracts like many American CRTs do

2) 1961 CGE, this set uses a 17" 110° CRT and an one-piece bakelite cabinet.

3) 1964 Phonola 23", this set uses the world's first CRT (the Philips A59-11W) with the modern "rimband" type of integral implosion protection, the screen is the actual face of the CRT envelope

i also have an Italian-made Emerson, i'll post a pic of it ASAP

Here are some pictures of my Sentinel 424 from 1951!

A vintage photo of some test equipment for TV and radio work. And a radio chassis. Photo taken in the early 60's. And that's the family cat, named "Silky". An Eico 'scope (which was little more than a toy compared to the Tektronix scopes I've used in my jobs as an electrical engineer), an Eico TV signal generator(?), Hickok vacuum tube voltmeter(?), and a simple emissions tube tester.

Found a stand!
 

Not something I'd normally bother with but it's kind of neat looking, no doubt the word "Deco" would apply on eBay. :scratch2:

I thought it was some kind of kids chair at first but then i noticed the wheels.

It's probably deep enough for a color set but this Zenith fits nicely on it.

Though not a collector (yet), I picked up a 1949 Arvin console tv from a friend. It doesn't work, but my father is optimistic he can get it going (old tube tv guy). Its in pretty good shape for 60+ years. I've thought about refinishing the cabinet, but probably won't. Its a 12" round set. Don't know how much the old Arvin sets are worth (don't see many). I paid $5 from a friend for it and he paid less than that. What's neat is I live in the town this was made in. In fact, it was purchased at a flea market in one of the older Arvin factories, I think where they had a TV line... talk about coming full circle.

If I get approval from domestic management (wife that doesn't understand...), I'm trying to aquire a newer Arvin table top model (looks like about a 19" square tube) that I think does work.

Man! Some guys have all the luck!! That Arvin is a REAL nice looking set! Where is MY piece of the pie? What a way to start a collection.....

thanks. It's not quite as nicce in person. The console is pretty scratched up & is on the edge of being refinished. however, I would have a very hard time trying to match the finish (I really don't want to disassemble the whole thing and risk screwing it up). It does fit in nicely with the 1950's wooden exec desk & cool flourescent desk lamp (60's?) I have. Sad thing is I used to have a mint Admiral console stereo that would matchc perfect. Had to rehome it when we remodeled the downstairs. I still regret getting rid of it, but it did go to a good home.

Good catch on the Arvin! I see there radios but the TV's don't show up much. I have a few different Arvin stereos. They're a long way from high-fidelity but there is something about them that I like.

Here's the beautiful Motorola 17T13 I bought from Tubejunke !! It is one sweet set !

Fada 799
 

This is one I bought on eBay several years ago and have just gotten around to restoring.

Most of the 'lytics showed good ESR, low leakage, and were within tolerance. Those that didn't meet the test criteria got re-stuffed with new units. For replacing the paper/wax caps, I used Mallory "150's" tubular axials, as I've gotten a good performance / price balance with these. Still needs hooked up to the scope/sweep/markers to check the RF/VIF/SIF, and video amp response curves. If it needs alignment at all, it will clearly need only the procedure shown under "touch-up alignment" in the 630TS service manual. The set is now protected by a 5A fast-acting AC line "pigtail" fuse (beside the filter caps), 1A main B+ "pico" fuse (under the front 5U4 socket), and 250mA B+ Boost "pico" fuse (under the 5V4 socket).

Final assembly will be after response-check and (if needed) touch-up alignment, but here's a screenshot, underchassis view, then the cabinet. Note the cardboard shield which protects the "unobtanium" electrodynamic speaker until the chassis is safely inside its cabinet.

Curtis Mathes TV/HiFi combo "wall unit" ...
 

This one isn't my personal set, but it's a beautiful example of my recent work. It got all its 'lytics checked for ESR/leakage/tolerance, one single-section (cathode bypass) 'lytic flunked and was replaced. Swapped out 45 bumblebee caps, cleaned everything up, and changed some weak tubes. HiFi is in the drawer below the TV.

Thanks to Steve McVoy for the referral. Working on an RCA metal portable for the same client now and will post pics when finished.

Wow, that Curtis Mathes makes the "single wide" color one in another topic seem small! :)

I love the small CRT you have for the Fada project. And, "unobtanium electrodynamic speaker"... I have a 630TS that had been converted to a video monitor at some time, and a video-level control or something was mounted through the speaker grille cloth. I tried some kind of speaker as part of my repair attempts around 1980 but got no sound. Now I think I know the main reason why. I will have to look at the Photofact manual closely at some point and figure out how to make a PM speaker work in there. I do not remember if the audio-output transformer was even still there.

Reply to questions / comments.
 

The original RCA service manual (as a 90 MB "pdf" file) is available for free download here http://www.antiqueradioshop.com/RCA630TSService.pdf, linked from this illustrated case history on a 630TS restoration http://www.antiqueradio.org/RCA630TSTelevision.htm.

The 5" CRT pictured is type 5AXP4, designed specifically for use in a repair shop environment. These can be found occasionally on eBay. Most 1950's vintage tube manuals having a "picture tubes" section include the 5AXP4 characteristics under "test" picture tubes.

Obviously-modified sets can be frightening. As long as the mod was added through the grille cloth, though, that should be a relatively simple fix to obtain some reproduction grille cloth of the proper style from AES, provided the IF wasn't gutted. Field coil is 62 ohms and voice coil is 3.2 ohms as I recall. The modification probably included a filter choke subbed for the field coil.

I just burned a DVD today of my new "Angel Head Test Pattern" which I drew on CAD software, superimposed a small photo of the family dog on one side, added a 400 Hz audio tone and transcoded to a video slide show. I may be offering that DVD on my web site soon.

The TV and HiFi sections of the Curtis Mathes "wall unit" slide out for easy servicing and all the "service" adjustments (height, linearity, AGC, etc.) are accessible from the cabinet front, concealed behind the large channel selector knob. The TV section itself isn't much larger than other 23" B/W consoles of early 1960's vintage. There are two sections to the TV chassis, forming an "L" shape as viewed from cabinet rear. Low-voltage power supply and horizontal sweep are on the horizontally-mounted subchassis, the entire signal path from IF to audio, video, and vertical sweep are on the vertically-mounted chassis behind the control panel. Terminal strips are thru-chassis "pin" type similar to those Zenith used in the 1960's. Tuner is a 12-channel turret type with silver contacts.

I may have posted this in the past but I was going through some stuff and came across this old photo of an RCA that was being given away by a theater as a promotion.

I have the exact same model set that I rescued from the back lot of a thrift store more than 10years ago. It's basically restored and working now (with a NOS 16AP4) but I haven't gotten around to finishing it.

In the actual photo I can read that it was the Fox Wichita Theaters and Continental Grill that was sponsoring the giveaway, anyone recognize the place?

Edit: it could be the Orpheum? http://www.wichitaorpheum.com/pictures.php http://www.wichitaorpheum.com/pictures.php
And this shot 3rd photo, looks like the spot where the set was sitting!

http://i65.photobucket.com/albums/h2...s/100_0581.jpg This is My Admiral 19A11-SN I acquired from ebay. Its a very clean and the chassis is rust free and unmolested. I have the caps on order and look forward to restoring this set.http://i65.photobucket.com/albums/h2...s/100_0599.jpg This is my Sony TV-740 I bought from a thrift store for $3. The set works fine. I have added an video input through the UHF connection which is turned on or off through a switch I added.http://i65.photobucket.com/albums/h2...Photo-0011.jpgThis is My Motorola VT-71 I purchased from an antique store for $75 (sorry for the bad pic) it is in unrestored condition and in Las Vegas with the rest of better radios.

This small CRT mounted (a temperary service install) reminds me of s small hole of a company called Matrix Instruments I worked for back in 1979 (just out of college) that made machines that would take video and project it onto Xray film to create hard copy in the form doctors were used to working with back then. Except we used solid state Conrac black and white monitors like their model "QQA" and replaced the big CRT they came with with small flat screen 5 inch CRTs. This would then be installed inside a black metal cabinet with the CRT facing up, aimed at a camera lens with shutter that was part of an Xray camera system. Stupid little product, but thet sold a bunch.

heres my westinghouse,i restored the cabnit,but with my uncle arthur acting up (im only 25 wtf:tears:)in my hands i really cant do anymore than replace the bad tubes,i hooked up the vcr and put in a tape of "SHINDIG WITH JACKIE WILSON".as you can see the vert and horz is off.

Now, THAT is a TV I would lovingly restore to Like New Condition.

If anyone can put Me in contact with someone who wants to part with a good, origional condition TV like that, I'd appreciate it...

LJB:smoke:

A friend of mine has one of them, and, I'm trying to persuade him to part with it. Does yours work? Any unusual difficulties in restoring it?

LJB:smoke:

Hmm, where did you say you were located? :scratch2:

M3-SRT8, my Westinghouse does work well. The restoration went smoothly, a standard re-cap of the wax papers and electrolytics, and a general check-up and replacement of anything else way out of tolerance. No troubles with the HV supply. Good luck!

Ooooo....Worcester, Mass.

That might be a problem.
