RCA/Philips Projection set
|
Very interesting.
|
Oh no, not a home-brew at all. That unit is a Norelco "Duo-View" B&W projection TV adapter. The customer would purchase the (lower) unit, which consisted of a cabinet containing the projection optics and CRT (3NP4), HV power supply, horizontal and vertical deflection circuitry, LV power supply, deflection failure protection circuitry, and a cathode follower for the video. Video and horizontal and vertical signals were taken from the customers TV set as inputs to the projector. A band switch in the projection unit allowed the customer to either watch the TV or use the projection unit to display up to a 3' X 4' picture on an external screen (in a very dark room!).

Looks like a VERY nice arrangement. If I had lived in those days, I would have liked to have something like this myself!
How reliable it was? |
Geez! I would think there would be some serious collectors driving the bids on that thing beyond $66. No telling what the reserve is.....
I have an 8T-243 that is very similar. Top portion that is, although I am not lucky enough to have the double D crt border surround. Instead mine has the uglier rectangular style. I have always wondered why some sets with round crt's had double D and others rectangular. Anybody know?? |
Double D masks came into vogue shortly after the first porthole sets appeared. Generally speaking, 1948 and earlier sets had rectangular masks; 1949 and later sets had double D masks.
Why? Bigger image--at the expense of the corners. Apparently a negligible expense. |

Sparton

Here is a set I love. It is a Sparton from I would say the early 50's. I bought this set while still in everyday use back in the 80's. I have kept it all these years because it seems to be indestructable. Also I have never run into another so it may not be what you would call common. It looks like Sparton really made a good product. Around 50 years of service unrestored!! :thmbsp:

Agreed. |

I have the console version of that Sparton. It kind of works as received, but I need to re-cap it.
|
Really I should re cap mine as after all these years the horizontal size takes a few minutes to fill the screen, and after about 20 minutes the vertical size starts shrinking at the bottom. Very likely these are both cap issues, the later may be a resistor changing value after heating up.
I say this set would go another 50! Its built like a tank. It picks up channels clear as a bell with NO antenna, and the raster is bright and crisp as any I have ever seen. Does anybody know how Sparton ranked as far as quality? I would compare it to the quality of a Dumont myself.... |
Couple of interesting sets. Middle of nowhere.

kbmuri,
Great catch. http://cgi.ebay.com/RCA-Victor-1947-...d=p3911.c0.m14 I'm not sure how this is still working, but it is and should be snapped up right now. Dave A |
It's the same seller who has the CTC-4 on the ETF site. He also had a Zenith like the one in my avatar.

Big screen 630
Saw this earlier this week as part of a massive estate sale. Now it is being parted out. Looks like a 12" upgrade of the classic 630. No HV cage cover. Not mine.
It is near me and I can pick it up and deliver to Kutztown on Saturday only. Pricey at $300. Make offer. http://philadelphia.craigslist.org/clt/818867509.html |
Cool looking Sylvania!
