Ok, I'm completely speechless. That doesn't look anything like my set, which is a shameless ctc15 copy, using RCA boards, with RCA resistor and capacitor numbers silkscreened on them, even though Silvertone used different numbers on the schematic.
There were Silvertone roundies with no power transformer. Someone posted about this in an old thread. I looked through some old schematics and found one for a Silvertone 61731. It has a 10le8 single tube color demodulator. I think this was used in Olympic or maybe Motorola sets. Does anyone remember? This one didnt give a CRT number, but the setup instructions look like roundie.
While l was looking for that, I found a schematic for another transformer type set. It is a Silvertone 5170. It has a 400kb22 crt and some weird 6r-p22 color matrix tubes. The rest of the tubes are normal american types. Could It be japanese? Theres no picture of the set, but the drawings in the setup instructions suggest it is a roundie. It doesnt look like yours either.
So, when we add yours to the mix, thats at least 4 completely different types of Silvertone roundie chassis. I had no idea there were so many. What Sams are you using? Does the circuitry look like RCA?
Thats a really cool looking set BTW, and a terrific picture
