William Englebert Fahrenfeld and his TV
 
I took a trip last weekend to NY to the home of William Fahrenfeld's granddaughter. I went to pick up William's first television, an RCA TRK-5. When I arrived and saw the set for the first time I was speechless. I spent a short time speaking with the family about William, the TRK-5, and their history. I am still working with the family to write a history to share with the collector community.

This is William at age 24.

I have spent the last five days cleaning and photographing the set. I have no plans to electronically restore the set. There are only a couple of aesthetic things I plan on fixing, more on that later. For now the set is in many pieces, once I fix those few issues I'll put the set back together.

TRK-5 deconstructed.

What a wonderful find and in the condition the photos show. I will let others argue about restoration and settle for William's vision of buying a set like this and what he thought would come of it. Only he knows and maybe told the family for you to enlighten us later. Congrats.

Geist 02-22-2013 06:33 PM

Hi VTS1134;
Congratulations, How did you ever Run into this, or become aquainted / Find out about it ??? What is the History of Your finding this ?? Please fill us in more.. I would be interested in more close up pictures of the Chassis both out side and bottom inside.. When was this built ?? And what CRT Tube does it use ??
THANK YOU Marty

Sandy G 02-22-2013 07:27 PM

I think these sets were from 1938-40.

Zenith6S321 02-22-2013 07:28 PM

The cabinet is in absolutely amazing condition! It obviously has been well cared for by people that recognized its historic value.

What a treasure, like the proverbial "57 Chevy in a barn"
That speaker looks like 12 inch and probably had fantastic TV sound.

baursam 02-22-2013 08:36 PM

Beautiful set!!! Soooo jealous!! I have dreams about finding one of these. Sadly, its not going to happen around here. Congrats!!

bars&tone 02-22-2013 10:58 PM

Congratulations! Great find! I'm looking forward to hearing more of the story as well.

Handsome guy, but who shoved him in the mud on the way to the photo shoot?

rld-tv01 02-23-2013 07:37 AM

Congratulations, I have been looking for a TRK5 or TRK9 like your find for many years. It seems you have been extremely lucky recently in your TV finds. Like the others I am interested in how you tracked it down.

vts1134 02-23-2013 08:51 AM

My first hurdle in putting the set back together is the radio bezel. The bezel has shrunk from it's original size. The shrinkage has cracked the bezel around the top left mounting screw.

http://i1075.photobucket.com/albums/...ps83743801.jpg

I'm not quite sure how to remount the bezel. Should I drill a new mounting location to take the strain off of the bezel in that area? Should I simply leave that screw out of the front? What do you guys think?

The next issue is cleaning the dial glass. I have cleaned the rest of the bezel, but I didn't touch the back part of the glass. I was haunted by visions of me wiping the decals of off the glass so I left it alone, but it could definitely use a cleaning. Were my fears warranted, or can I simply buff the back of the glass with a damp cloth?

http://i1075.photobucket.com/albums/...ps9587c977.jpg

The last issue with the bezel area are the push buttons, they are long gone. The tenite just couldn't hold out for 74 years. I am going to have to order reproduction replacements. Does any one know if the radio bezel has to be off of the set to install them?

I think I have been very lucky recently. I can't say exactly how I found the set, it sort of fell into my lap with the help of a friend. I have been seeking to acquire a TRK-12 since I saw a picture of one three years ago, but I couldn't say no to a TRK-5.

my great grandma had a trk 9 complete when she moved
she threw it in the trash!

I need a new reproduction of the whole dail and bezel ,I bought the set at local flea market for $20 bucks..3 years ago and needed a new bezel and dial glass badly..it suffers the same plastic diease and the push buttons are shot also! Jody

John,
I wouldn't drill any new mounting holes. This would only be a temporary solution as the tenite will continue to shrink and crack around the new hole location. There's nothing you can do. Either leave the screw out or just put it back in barely snug so it can move a little. That's all I do with them.

This bezel was used on a handful of RCA radios at the time but they are nearly as hard to find as the tv's and usually in just as poor condition.

Just use a soft brush like those for cleaning a camera lens. Never use any liquid on the printed side.

The bezel does have to be off to install the buttons. The small lip on the bottom edge of the buttons catches the back side of the bezel to keep the buttons from coming out too far, that is if the bezel isn't so distorted that they'll come out anyway.


What are the brand and date codes on the tubes and crt? It would be interesting to determine how long the set was in general use.

DavGoodlin 02-23-2013 10:42 AM

There is a producer of bezels (old time reproductions? in CA) for Philco radios that sells through Radiodaze. Maybe they would comission one.

47'Plymouth 02-23-2013 10:59 AM

I'd go for it...a bit pricey,..but worth it:banana::banana:let me know when ones available:yes::yes:Jody

kx250rider 02-23-2013 11:58 AM

That would be worth having a new bezel made by CAD/CAM, and I bet it could be done on a low production scale. I know a hobbyist who is recently retired from a career in mil-spec machining, and he has "made" perfect reproduction laser-cut pocket watch parts, antique car parts, etc. He could probably do it, but I'd have to get his permission to give out his name. He just spent more on a hobby workshop in his barn, than it would cost to build a whole 5000-square foot house. He installed all the technology he knew at work, and has it all set up.

Charles

Chip Chester 02-23-2013 02:31 PM

There may be a 3D printing option on the bezel, too. But no-one knows if that stuff will last 70 years, either.

I'm not any kind of qualified restorer, but that won't stop me from sharing a thought: Perhaps a thin sheet (1/16" or less) of aluminum, brass, etc. in the original outline of the bezel, with the original bezel aligned as required and mounted to the 'shim'. Paint to match original bezel as much as possible. Attach shim to original wood holes, (hiding the finish issue) and attach bezel to shim in a manner that allows 'creep' without 'crack'. That may be black plastic or nylon phillips machine screws in to tapped holes or soldered-on threaded plates, or the like. The plastic/nylon would give a bit, allowing original bezel to move without cracking more.

If the black nylon screw head looks out of place, then perhaps use a flat-head screw and affix a sacrificial black steel phillips head (only) to it... basically as decoration.

Yeah it's a lot of work, but you've got a pretty good head start overall!
Nice example.

Chip

Sandy G 02-23-2013 03:25 PM

I would put in a plea to at least ATTEMPT to do an electrical restoration, as well...You might get lucky & end up w/a WORKING pre-war TV...How KEWL would THAT be ?!?

I've never read date codes on tubes before. Where would I find them?

vts1134 02-24-2013 06:55 AM

I was able to find some date code info on the net. I could only find out what the first two digits of the three digit code stand for. Every tube in both the radio and television chassis, except for one, are RCA branded and coded KE5, XE1, XE2, or XE3. That means 1938, and 1939 OEM for the first two digits, does the last number indicate month? The only exception in the set is the horizontal output tube which is branded National Union. The only coding I can find on that tube is an "F". I don't have a tube tester so I don't know how well used they are, but maybe the set was used so little that the tubes are all original?

RCA codes of the era where 2 or 3 characters long. The first character was the year such as R-1939, X-1940, Y-1941 followed by the letter E for OEM, followed by the month; 1-Jan-Feb, 2-Mar-April, etc. The XE1 for example is 1940, OEM, Jan-Feb. The KE5 is 1943, OEM, Sep-Oct.

Unless the National Union tube is new enough to be labeled under the EIA codes (247 would appear somewhere on the tube for NU) there's no way I am aware of to date it. The fact that all the other tubes appear to be original except the KE5, would suggest the set was not serviced much past the late 1940's.

Larry Bordanaro has been very ill and it is uncertain if he will continue making reproductions. Ed (blacksmith) at Renovated Radios has done some bezels but both these guys need fairly good originals to start with since they do exact copies. They can create successive master to straighten and shape a bad original, but the worse it is, the longer and more tedious this becomes.

Ed has investigated 3D printers but none of them give a good surface finish so the entire part would need to be sanded and polished (if the material is hard enough to accept a polish) and if it is intricate this can be difficult if not impossible. CNC can't make these swirled plastic parts unless you can find some swirled plastic material to start with. A CNC part could be used by Ed or Larry to then make a mold to cast parts, but even a CNC part takes considerable amount of sanding and polishing to create the mirror finish.

Steve McVoy 02-24-2013 07:35 AM

Reproduction pushbuttons are available here:

http://www.renovatedradios.com/parts.html#pushbuttons

There are a number of RCA radios that use similar bezels. The difference is that the TRK-5 bezel uses aluminum pieces around the eye tube and electric tuning light, while the bezels from other RCA radios either have no pieces or have pieces that are silver. It is easy to remove the painted pieces from the old bezel and put them on the replacement bezel, though.

Here are some of the RCA radios with similar bezels:

98T, chassis RC-386A
98K2, chassis RC-386A

97K2, chassis RC-351K
97T2, chassis RC-351K

96E2, chassis RC-351L
96K5, chassis RC-351L
96T7, chassis RC-351L

Hi All;
VTS1134, You should be able to find another member in the Area of where you live who has a tube Tester, that could help you, determine how good the tubes are.. I have one that would do the trick but I live way tooo far away..
THANK YOU Marty

vts1134 02-24-2013 09:34 AM

Marty-
I have a local shop in my area where I test all of my tubes so I'm covered there.

I have the reproduction pushbuttons ordered and they are on the way. Since I have to wait for the pushbuttons to arrive before I install the radio chassis and bezel, I'll put that on the back burner.

On to the television chassis. Looking over the underside of the chassis I can see that there was repair work done to the horizontal output circuit. That could account for the replacement horizontal output tube.

http://i1075.photobucket.com/albums/...psba7b8df7.jpg

Can any one spot anything else out of place?

http://i1075.photobucket.com/albums/...ps4753e9da.jpg

vts1134 02-24-2013 09:59 AM

The television chassis has suffered some damage. The fine tuning portion of the channel selector shaft has broken off.

http://i1075.photobucket.com/albums/...pseb649683.jpg

I am able to turn the fine tuning control from what's left of the shaft, however it simply spins freely, the shaft must be broken internally as the fine tuning capacitor (C9) does not move. I thought perhaps the capacitor could be seized, which would account for the breakage, but I can adjust it manually.

http://i1075.photobucket.com/albums/...ps64b82a65.jpg

I am considering a repair to this part of the set depending on difficulty, and whether or not an original shaft can be found, or the original repaired.

tubesrule 02-24-2013 11:34 AM

John,
Those replaced caps are the horizontal deflection coupling caps and are always bad. They did take a while to go bad originally which suggest this set was used for quite some time. It's too bad that the original caps are gone as it's quite easy to restuff them with modern 3000V caps. You'll need to find caps of the correct size or cardboard tubes that can be dyed to match to use for restuffing.

The two large caps on the opposite side of the board with the yellow and green heavy wires going between them are the vertical deflection coupling caps are are most likely bad.

Your fine tuning control is working correctly. The shaft is supposed to turn freely. If you look at your picture of the trimmer cap, the aluminum piece on the end is cup shaped. The black rubber piece is attached to the end of the brass shaft that goes through the main tuning shaft and is shaped to fit the cup. To adjust the fine tuning you have to push in on the shaft to make the rubber piece turn the trimmer cap.

The fine tuning shaft can be fairly easily replicated although it's a little difficult to install since it's rather long and you have to remove the trimmer to get it in.

leadlike 02-24-2013 11:58 AM

Just wanted to throw in my own .02:

If it were my set, I would seriously just leave it all as is. It appears to be unmolested with a decent (though slightly alligatored) finish. It has almost all of its original tubes for crying out loud! I would think it more prudent to preserve this set as "all original" as possible. Maybe find a HO tube that is an RCA from the right era, replace the horizontal coupling caps with what was originally in there, etc. Just to make it as stock as possible.

I just don't feel there is much to be gained from restoring such a rare set. I think the tuner would need to be modified to receive analog signals anyway. With less than 20 of these sets surviving-and all that are documented on the internet seem to have been heavily hacked up at some point; I would think it would be far more important to keep one of these in its 1939 splendor.

Think about it.

I've already thought about it. On my original post I said I have no plans on electronically restoring this set. I also feel there is not much to be gained from making this set function again. I live close enough to the ETF museum to take a drive over to see one working if I really need to see one function. I am going to make the few repairs needed to the set, replace non-original parts with originals, and call it a day. I have restored sets for display, this will be a non-working original set for display.
I would very much like to find original capacitors to replace the replacements if anyone has them.

Steve McVoy 02-24-2013 12:40 PM

We may have some original capacitors (bad, of course). Send me a list of what you need and I'll check.

vts1134 02-24-2013 01:03 PM

The two caps in question are both .005 mfd 3,000 volt caps. Bad caps are no problem, as long as they are period correct.

vts1134 02-27-2013 06:08 AM

Took another long look under the television chassis this morning and spotted two more replacement capacitors, C71 and C73. It appears there was some problems in the vertical at one point or another as well. I'm sure capacitors of this vintage are not your every day item but I'm searching for them non the less. The four capacitors I need are:
2-.005 mfd 3,000 volt (mentioned above)
1- .25 mfd 200 volt
1- .1 mfd 400 volt
Again, these capacitors need not be functional, just period correct. If any one has these capacitors, or just advice on where I might be able to look and find them, I'd be grateful.

tubesrule 02-27-2013 09:26 AM

The cardboard sleeved low voltage caps that RCA used were in all of their radios and tv's of the era and are easy to find. Those high voltage caps were only used in the TT-5 and TRK-5 so unless Steve comes up with something the chances of finding originals is extremely slim.

vts1134 02-27-2013 09:48 AM

Thanks Darryl.
I also need a replacement horizontal output tube- 6F8. RCA branded, date coded XE_. I asked my local guy that I get all of my tubes from but he doesn't have any RCA XE_ coded 6F8s. Again this tube does not need to be functional, just needs to look the part.

Steve McVoy 02-27-2013 09:53 AM

Here are a couple of pictures. The black and white one is from 1939, the color one modern. I suspect that RCA may have used more than one style originally.

tubesrule 02-27-2013 10:26 AM

Steve,
I think those are the same cap, just a difference in lighting. The high voltage caps always seem to have that dark tan, extremely hard material used for sealing the ends.

96K5, chassis RC-351L
96T7, chassis RC-351L

I received the repro pushbuttons in the mail yesterday from renovatedradios.com. I'll have to fabricate the mounting rod that holds them onto the radio bezel, more on that later. I also need to create the pushbutton labels for each button. Chuck Azzalina's site has a good shot of the labels that he made for his TRK-5.

http://www.myvintagetv.com/trk5_pushbuttons.jpg

Has anyone else made labels for a TRK-5, or any of the radio models Steve mentioned that use a similar bezel? Does any one have original labels for any of these models that they could photograph for color and font reference?
