Its getting to be time to start listing available items, in the live auction, in the
silent auction, and even in the flea market, as they get known. I'm definitely a buyer ... but what am I supposed to drool over until April 30? Wanted: more of what sold for big bucks last year. (I am happy with what I took away, a TRK12/120, but I already owned it, so I would have had to leave what I bought at the museum for another trip.)

The Automatic TV-709 looks very much like the same schematic as a
Tele-Tone TV 149 The Sylvania color appears to be the 31T304 "The Granada". Is it too a CTC-4 clone? IF not, what is it or a schematic? Is the Indextron CRT good?

The Sylvania roundie looks to be very similar to the 21 inch Hoffman, the 21 inch Sentinel, and a few other sets that used what Ed Reitan referred to as the 'Licensee Labs Circuit'. It's basically a cheapened CTC-4 with the HV section of a 21-CT-55. They're interesting, but not very good performers.

That Sylvania set is indeed a model 31T304, "The Granada". Its listed in the 1957 Color Television Book and is NOT an RCA clone.... It uses Sylvania's own chassis design and convergence design..... It in fact has both a vertical AND a horizontal chassis. That has to be one of the rarer color TV's from the 50's..... I saw one many many years ago at a Sylvania Dealer....but it was very rough and mostly in parts. I believe that Sylvania never sold these sets to the public but dealers had them mostly for promotional purposes..... That's a rare one for sure ! I always wondered if these sets had Halo Light around the color picture tube?

There are 4 surviving sets, so I think it is probable that Sylvania did actually sell them to the public, but we will probably never know for sure.

Item 51 & 52, the Tektronix 650 color monitor
This model would be worthy of a thread, they were so extremely over engineered The 4 knobs had detent position called Cal (calibration preset) Used early Sony Trinitron picture tube that only had around 300 lines H resolution But had massive complexity & number of ICs and used digital countdown to derive H & V sync (a long time before consumer sets did this with LSI chips)

Two weeks until the convention starts. If you plan to attend, and haven't registered yet, please do it now, so we can get an accurate count for lunch and dinner.
