The lost years?

[Charlie]

Today, I was looking for a schematic on an AM radio, and stumbled across a Sams for this television. It's a Truetone color set from the late 50's (sams 382-3 Dec. 1957). I do not recall seeing one like this on any of the various TV sites. I thought it was kinda interesting because of the brand. It isn't one of the typical major brands of color television that we are used to seeing.

This set uses a 27 tube verticle "donut" chassis surrounding the neck of the 21AXP22. It uses selenium rectifiers for B+. Audio goes out two 6 x 9 speakers. It does not appear that an optional UHF tuner could be installed.

One thing in the schematic I found to be odd... the power transformer suppies all of the tubes their heaters except for one... the 6AN8 AGC tube has it's own 6.3 volt transformer. I couldn't find any other tubes other than that one using that transformer. I might have missed something, but that's the way it looks.
