The Rider's is wrong. I've attached a scan from an original Motorola schematic.

My scan came from a Wallace's Telaide 1946-1951 volume one. Who knows where they copied it from. Those dots sure make a difference
That's some cool looking vintage coax in your set. I'll see what I can scrounge up.
Look how simple that contrast control was in the earlier TS-4 chassis. I think the extra components in the TS-18 are an attempt to suppress the vertical retrace ?
