Creating a Frankenrola Set
 
I picked up this Motorola TS-60 chassis a while ago with the intent of parting it out. It was in such good condition that I never did though. The previous owner is a radio restorer and couldn't get it to work. Looks like he did excellent work to me. It probably came from a 16T1 like this.
I packed it away and almost forgot about it.

Well a few weeks ago I came across an empty Motorola bakelite cabinet on ebay. It's for a model 17T5E like this.

I had the seller take some measurements and it seemed that my 16" chassis would fit nicely so I took a chance on it.

Now I had to worry about shipping damage. It just arrived today.

Looks good so far.

Hurray! It survived :banana:

Better yet - it's a good fit :D

The seller included these knobs. I believe the large outer knobs are correct. I'm not sure about that inner one though :scratch2:

So what do you guys think about me creating a Frankenstein Motorola set ?

Looks like a great fit to the 16KP4 (or similar) crt... wonder if Motorola got a bit carried away using the "17" in the model number for the newer cabinet? Bet a 17BP4 (or similar) would not match the mask as well.
I would do it without hesitation!!!:thmbsp:

Update:just dug out a Sams #167 folder 13 (5-52) for the model 17T5E,F (as well as the 17K10E, 17T6G) chassis TS-314A,B,TS-315 A,B... and the jug is shown as a 17HP4,17TP4... wonder why your 16" fits so well? :scratch2:

Go for it! It looks good and it's better than letting them both just sit unused.

Looks like you were saved a lot of work recapping that chassis. Assuming you can find the problem without too much work.

Was the cabinet double boxed or was it shipped as seen in the first open box photo? If it was just a single box you were really lucky that it arrived intact!

It was sort of double boxed. The two boxes were a very tight fit - no packing in between :no:
Once I clear the Motorola 19K1 off my workbench, I'll try powering this chassis up.

Dunno. There is a slight gap on each side as the mask has a slight curve to it while the 16KP4 is very flat. I'm gonna try using the mask that came with the 16" chassis and see if it fits any better. I'd like the chassis to slide forward another 1/2" or so if possible.

bandersen 08-15-2010 02:47 AM

The 16" bezel was a flop so I'll stick with 17" one. I spent a little time tonight on the cabinet. It's dirty, faded and scratched up so I'm going to try wet sanding.
http://farm5.static.flickr.com/4098/...6c908347_z.jpg

First up a little #600 on the worst scratches. I got them mostly out but was nervous about breaking through to the pulpy filler material.
http://farm5.static.flickr.com/4102/...b3429365_z.jpg

Next, 1000, 1500, 2000, 2500 and 3000 grit sandpaper.
http://farm5.static.flickr.com/4138/...449d045d_z.jpg

Here it is post sanding.
http://farm5.static.flickr.com/4137/...5bdcda85_z.jpg

Here it is after buffing with Novus #2.
http://farm5.static.flickr.com/4094/...139f832e_z.jpg

Finally, I buffed it with Simichrome metal polish. It came out quite well. That leaves the sides to do.. I'll save that for another day.

That bakelite cabinet set probably came with a 17TP4 metal CRT. The curvature of the face of a metal tube is closer to a 16t than 17 in. glass tube. P.S. Someone spent a fortune on those can lytics. Dave.

Looks like a reasonable plan. Two orphans meet by chance and it's a marriage made in heaven! You're not doing anything destructive, so if by some miracle you later find a correct chassis for one and a correct cabinet for the other, you can do a swap and make the museum curators happy.

Great job bringing that bakelite back.

Good thought! The PF that I have clearly shows a glass tube in the set, but also shows a two gaps between the corners and the center of the left side and bottom side. The bottom of the bezel shown in the Photofact pix in the first post on this thread appears to have been re-drawn, and does not show the two gaps that are visible in the orig pix. (see Pix 1, below)

I have seen earlier models of this set with 16" CRTs... so perhaps designers only slightly modified the older bezel design, so that it could be used (with slight mis-match) with either the glass and metal 17" tubes. :scratch2:

Later, Motorola dropped the strict 4:3 look and redesigned the cabinet and bezel for the 17" "rounded" CRTs ... Pix 2, Model 17T11.

He sure did. I actually asked him about that once I noticed them. He had them custom made by a company that's no longer around :(

I think this is the first time I've seen wire nuts used in a TV!
http://farm5.static.flickr.com/4142/...0a7d30b7_z.jpg

I did find a few bumblebee caps lurking and some questionable looking repairs. I'll know more once I get it up on the workbench. I have to finish the 19K1 first though.

Here's a closeup of the screen surround and plastic logo. What do you suppose this coating was originally ? It looks to me like corroded copper or brass plating. The cabinet has cleaned up quite nicely otherwise.

I figure I have three choices.
  1. Leave it alone.
  2. Remove it and buff the underlying bakelite.
  3. Try to re-create the original finish.

Any ideas ?

That gold coating around the CRT is what to me looked like just a sort of semi-flat, slightly textured paint. I had one of those for years until some guy from Massachusetts came here to VA (around 800 miles one way) and bought mine. And for the record, the CRT was a glass 17 (?) incher with the bakelite case. I have another Motorola with that chassis in a wooden case. They must have been built with the best of parts because I have had three with the similar chassis and all three were basically plug and play for at least a while before caps started causing troubles.

RitchieMars 08-28-2010 01:16 PM

I like like trying to recreate the way things originally look, and in this case I think I'd clean up those surfaces enough to paint them with some shade of gold, bronze, or copper paint. Once you clean the old finish away, you might like the bakelite ( especially considering the way turns out whenever you give it that special touch! ) so leaving it that way is always a simple option in case the paint looks like hell. Of course, that's why I'd try the paint on a smaller section first before I committed to masking off the whole deal. With a project like this, you're certainly entitled to take as much creative license as you want. :yes:

Eric H 08-28-2010 03:43 PM

I'm going to suggest some Dupli-Color Gold paint.

The same color that was found to be an excellent match for the Gold tables on the little RCA 45 players.
I have a can at work I can get the number from.

None of the common bright gold paints on the market really seem to match the old stuff of the 40's for one it seems to be a lot thinner, it also seems less "Green" but maybe the old paint tarnishes somewhat over the years?

bandersen 08-28-2010 09:18 PM

OK, I'll give painting a shot. Masking those curves is going to be a challenge I think.

Amazingly, three of the four chassis mounting screws line up perfectly. The fourth doesn't because of the cutout for the tuner.
