Scott 6T11 projection TV
 
Thanks to oldradio99 and wiscojim, I received a tip about a Scott projection set in miserable condition and some TV test equipment. I made arrangements for a visit and stopped by earlier today.

It turned out to be a little storefront / home that needs to be cleaned out in a few weeks for the new owner. I spent a few hours helping sort through stuff, offering my opinions on value and setting aside a few items for myself. They seemed genuinely surprised I offered as much money as I did for the lot. So both parties think they got a good deal :)

Here are some photos I took while poking around in the basement.

They had a matching pair of these Sentinel TV cabinets. Too bad they were empty and water damaged. At least I managed to salvage the big field coil speaker from one of them.

Sonora pink & white portable. It's a mess but kinda cute so I brought it home.

Now for the Scott. Not for the squeamish.

Apparently, it had been in great condition until a pipe starting leaking water right on top of it :(

Wow, great find! Too bad it's in such bad shape. But, if anybody can bring it back to life, you can!

I would say that compressor is for a refrigerator such as a grocery store case or small walk in. Colored bulbs were somewhat common in the 50's and 60's for mood lighting. The colors were very soft and subtle. Pink was commonly used in grocery stores to enhance the look of meats in display cases.

bandersen 11-30-2013 07:33 PM

Thanks for the vote of confidence. If I could find a local woodworker, I'd love to have a new top built.

It's hard to read but I believe the bulb carton says they "flatter complexions".

I found a little box of knobs that turn out to be for the Scott :) Now I just need to find the matching channel and fine tuning knobs.

What a find Bob! It pays to help clean up =-)
You could fix that top with a sheet of birch to make it solid again and match up a different species/finish veneer like the front.

bandersen 11-30-2013 08:50 PM

Unfortunately, it's worse than what these pictures show. One side of the cabinet is really bad too. Perhaps fabricating a new top from scratch and replacing the cabinet side is the way to go.

Kevin Kuehn 12-01-2013 01:40 PM

Looks like that was a fun place to dig around in. The Scott sure is interesting. Too bad about the water damage, but I'm sure you'll figure out a way to salvage most of it. Lucky how the pipe leaked slow enough that it never flooded the chassis.

I was really surprised to hear there were two of those same Sentinel consoles in that place. I brought home one of those exact sets earlier this fall, in rather nice condition, including a good 19AP4. Turns out it's a nice performing set, and the cabinet is real wood veneers, not a photo finish that was so common then. Sure would be fun to know the story behind why the owner ended up stashing those two empty cabinets down there. :yes:

bandersen 12-01-2013 02:02 PM

That's easy to explain. The elderly owner managed to make it down to the basement and commented that they had planned on making some sort of display cabinet out of them.

bandersen 12-01-2013 04:07 PM

Here's a closer look at the Airline Airline 94GSE-3011B and Sonora portable after some cleaning. Both CRTs test very good.

5th picture in the first post ? Sorry, I didn't take it and don't recall.

Well, even if the Protelgram ends up being a "Jonah", you got a SUH-WEET Airline & Sonora..

Yup, that is the pic. It reminds me of my VERY rare Electrovoice/Realistic Stereo-4 format Quadraphonic record decoder, but it is wider and does not have two knobs on the front like mine does so I'm guessing it is a different model or a related device.

Where those things really rare?
I had one and I scrapped it for parts. Don't remember where I got it!
That style enclosure was readily available as a project box.
BTW, did you see that early solid state B/W Zenith portable, behind the Airline portable. :scratch2:

Yeah they are the rarest of the quad record decoders that were originally marketed in the US. I got mine for under 15$ at an anti-q shoppe a few years back (probably the latter Bush years), and it was only this year that I saw another for sale in person. It was the first consumer quad record format available and did not get much support beyond Radio Shack. I've only been able to find about 4 records for my unit in all this time, and most of them were Realistic brand. I would imagine that on rarity alone the decoders must be worth a pretty penny considering what stuff of the more common formats goes for.

I never knew that those cases were available as project boxes...interesting.

That could be a Zenith back there...With how obscured it is in that pic I completely missed it.

bandersen 12-02-2013 08:07 PM

That's probably the 19" Zenith portable there that went to the scrappers. I would have sworn it was a tube set though. The back was missing and it was rusted out inside. I just couldn't drag everything home :(

bandersen 12-03-2013 03:26 PM

I just finished dragging up two flights of stairs :drool: I removed the power supply and receiver chassis, but even so my back is aching. It's a little bigger and heaver than an RCA 630TS and had to be tilted on it's side to fit though my door.

So now you can really see the extent of the water damage. I'm still amazed nothing inside suffered.
http://farm4.staticflickr.com/3715/1...ef1b1465_c.jpg http://farm6.staticflickr.com/5540/1...ffa7f674_c.jpg

I think that's beyond glue and clamping :tears: Probably an entire new top needs to be built, but perhaps the nice side walnut veneer could be reused.
http://farm4.staticflickr.com/3703/1...f40c19ca_c.jpg

This rail is crucial to the flip up screen mechanism so I'll do my best to repair it.

bandersen 12-03-2013 03:32 PM

I took a quick look at the service info in Riders vol #2 which mentions a speaker but I sure don't have one :scratch2:

They also show the tuner as having three tubes while mine only has two. I also don't the added on to prevent screen burn if the sweep fails. The serial # on the CRT Protelgram unit is 00028 so this could be a very early set.

That projection set is a great find and I'm so glad you rescued it. The cabinet is essentially a big box, so even if you have to build a new one, it won't require tons of fancy cabinetwork.

The same channel selector knob is used in the maker-unknown TV in my Scott 800B Combo:

http://antiqueradio.org/art/scott800b601.jpg

http://antiqueradio.org/art/Scott800BHiddenControls.jpg

It's similar to the main tuning knob in the 800B receiver. Cast metal with chrome plating. The small knobs are also identical to those used in the radio.

I have the Sam's, and it shows two different tuners used in that set. One is made by Sarkes-Tarzian, the other by General Instruments.

Unfortunately they each use three tubes, so I have no clue what yours is.

If you want me to send you the Photofact (no charge), PM me your home address.

bandersen 12-03-2013 07:03 PM

Phil, beautiful set and nice to know other sets use similar knobs. Jim, PM sent.

The chassis are aluminum which account for the lack of corrosion. They should clean up very nicely :)
http://farm4.staticflickr.com/3715/1...34496555_c.jpg

I careful cleaned around a stamp on the tuner with e q-tip and can just make out "Meck" and "TT10007". The tubes are 6J6 and 6AG5.
http://farm6.staticflickr.com/5480/1...c18ae23b_c.jpg


I see they used RCA components and design in the sweep circuits. That includes the typical flyback, 5V4, 6BG6 and huge power resistor used the 630TS, Admiral 30A1 and many other sets.
http://farm8.staticflickr.com/7431/1...1a16d3ef_c.jpg http://farm4.staticflickr.com/3746/1...1dc577ee_c.jpg

It looks quite primitive under the chassis.
http://farm6.staticflickr.com/5521/1...d74922e2_c.jpg

I just noticed "SAMPLE" is written on the chassis :scratch2:

Aww, Man... What I wouldn't give...I have a GORGEOUS 800-B chassis, & speaker...If I could just finagle a cabinet... Would be happy if it had no TV in it...

bandersen 12-03-2013 09:04 PM

I found the TT-10007 Sarkes Tarzian tuner mentioned in Riders volumes 6-9 as an option in some Meck sets. No schematics for it though.

bandersen 12-03-2013 11:25 PM

Here's a closer look at the options. Apparently this is two pieces of glass with something in between to form a corrective lens. Mine has gone a bit cloudy.
http://farm8.staticflickr.com/7452/1...221b9938_c.jpg

Here's a look down into the optical chamber. I've read that these mirrors are plated on the surface and shouldn't be touched.
http://farm4.staticflickr.com/3746/1...e9403d8a_c.jpg

Cleaning it didn't help any.
http://farm8.staticflickr.com/7459/1...19719559_c.jpg

The flip top mirror is pretty rough too. I hear these type of mirrors are very expensive to replace.
http://farm3.staticflickr.com/2883/1...8d25d7e6_c.jpg

I found lots of fantastic info and pictures in this thread. I'm jealous of those clean & shiny insides. Now I know where the speaker should be and all about the scan failure protection module. http://www.antiqueradios.com/forums/...81239&start=20

VintagePC 12-04-2013 07:24 AM

You're correct, any sort of optical grade mirror is usually surface coated instead of back-coated to avoid refreaction effects and other problems from having the light pass through the glass before being reflected. (IIRC you could potentially get double images in an application like this; a faint one from the reflection of the glass surface, and the "real" one from the silvered surface reflection) You can tell if this is the case by looking edge-on at the glass, that will reveal which side has been coated.

I wouldn't touch them unless it has a noticeable impact on picture quality; the coating was probably done with silver nitrate and traditional "mirror" making chemistry. It should be able to stand up to a _very_ gentle wash if it's only surface dirt, but I certainly wouldn't try anything more vigorous without a backup plan; you never know how storage conditions may have affected the coating's bond to the glass.

bandersen 12-05-2013 12:27 PM

All the mirrored surfaces have splotches that won't come off. No doubt from the nasty environment this set was stored in for years. I'll just leave them alone for now until the set is running.

I noticed some numbers peaking out from underneath the channel plate and decided to carefully remove it for a closer look. Here's what I found.
Perhaps this was for very early versions with a channel #1 tuner ?

Here's the set with the screen reinstalled. Those flimsy cardboard side panels have seen better days but should be easy to replicate.

The mirror in the lid might b cheaper to simply replace. There are places on the web which will sell you a front surface mirror cut to order for reasonable money.

My set has the same tuning knob, but the channel numbers (2-13) are decals on the wood panel. Not sure of the tuner configuration, its been a while since I was inside it, and as I acquired it already restored, never became that familiar with its inner details. It does have a sweep protection chassis.

Good luck! And keep us posted on your progress.

bandersen 12-06-2013 02:24 PM

Excellent! I knew some of you guys had mirrors re-coated, but wasn't sure where.

I check the 3NP4 for filament continuity last night and it's good :) Also no signs of burns on the face.

I've been through the whole set now, but have yet to find a serial # or date. This tag hanging off the HV box is the only label.
http://farm4.staticflickr.com/3776/1...bc0d189a_z.jpg http://farm8.staticflickr.com/7333/1...3a6ab9ea_z.jpg

The screen cleaned up fairly well. I don't think it's ground glass as I've read elsewhere though. It seems more like a coating that has chipped in a few areas.

Aren't the mirrors in all those projection TV sets we see on the curb every week front surface mirrors? If so, you could scavenge one for free.

Those likely aren't big enough; the optics in modern projection sets are very different and generally have only a small mirror (few inches square) in the back and a series of lenses to make the image fill the screen - they don't need as big a mirror because they don't have a collapsible front and can have a fixed optic path.

The last one I tore apart had a mirror that had to be at least 20 by 24 inches. This was from a large fixed-front projector set found on the curb, predating the DLP sets. They still commonly show up for free on Craigslist, or on the curb on days designated for large refuse items. Mine is probably in one of the storage bins now, I used to mount it outside by the bird feeder just to see what reactions I'd get from all the little critters. Here's a picture of a similar one found online.

Huh, today I learned. The only ones I've ever seen the inside of have had what amounts to a single lens at the back of the projection cavity with small mirrors somewhere in behind.

John Folsom 12-06-2013 05:05 PM

I took one of the rear projection sets apart (3 CRTs), and it had quite a large front surface mirror. But I managed to screw it up trying to cut it down to size.... so I would recommend taking any salvaged mirror to your local glass place and have them cut it down to size.

bandersen 12-06-2013 05:10 PM

Nuts! I saw one out in the trash just two blocks from my place a few weeks ago. It never occurred to me there might be anything worth salvaging in it.

Was it your first attempt at cutting glass? Mucked up my first crack as well until I got the hang of using/oiling the cutter and producing the "ripping silk" sound that indicates a clean cut that will break properly.

Obviously you'd have to cut the mirror from the non-coated side to get it to work.

I think all the projection sets I've seen may have been DLP, that could explain it.

Well, in all fairness, you didn't exactly have mirrors for a projection set to worry about at that time either... :D
