Has anybody ever seen one? Do any Rembrant's still exist?

Both the Early Television Museum and the Auman Television Museum have the tabletop version of the Rembrandt television. http://www.earlytelevision.org/rembrandt_1950.html Both of them have blonde cabinetts. I have never seen the console version. I think the Ambassador Starrett is a cool looking set and would like to get one. I thought United States Television only made projection sets until I found a console on Craiglist. It was in a barn on the Maryland/Pennsvania border and the guy said it came out of a bar in a nearby town. That USTV is not pictured in the add but is huge for a 12 inch set.

Here's what I can find on Zetka CRT's: their 15 inch flat face tube was a 15CP4, but was similar to Dumont's 15AP4 with an ion trap.

Zetka did supply other makers, but I can't find out who specifically. They were the first to make an all glass 16 inch tube, the 16DP4, where before there was only the metal cone version.

Zetka started around 1927 as a radio tube maker. In 1946 they were bought by U S Television Corp. but apparently remained a separate company. A guy named Hamilton Hogue was president of both companies. In 1950 they bought the patents for a color tv tube from a company called Sightmaster Corporation. Apparently nothing became of that and they soon disappeared along with UST.

I did find a report that UST started selling TV sets through Macy's in 1946.

Correction

In theory, it should be possible to modify the horizontal deflection circuits to run at higher scan rates. 480p (31KHz) should be doable, though going for 720p (43KHz) may be harder. If I could make 480p happen, it's an easy hop to 1080i (32KHz). Oh, the flyback times would stay about the same as for NTSC deflection rates, but that is almost a feature to make the picture be 4:3 as the sides of the picture would get clipped off, aka overscanned. The faster deflection rate probably demands more power than NTSC rates to make the picture the same width. The vertical would not need to be modified. The video amp stage may need more bandwidth, and remove the 4.5MHz sound trap and takeoff.

You would feed it with baseband HD luma directly, not thru the tuner and IF strip.

Anyone up for HD B&W? :D

I like the Rembrandt Dumont clones, never saw thoes sets before.

Modifying early postwar sets to show CBS color (29.16Khz) was only just barely "doable" if that's any gauge. John Folsom's CBS RX-43 prototype (really an RCA 9T24X) on working display at the ETF in 2004 was pushing the horizontal sweep output so hard that it had little red spots on the plate. This was apparently unavoidable in "normal" operation.

I was looking at my long eBay watch list on saw this United States Television (UST) projection set that has been on eBay for awhile now. Its on the wrong side of the US from me and a little high priced but its good to see some rare sets pop up for sale once in awhile.
