Your right Bob, I didn't catch the top symbol you circled for ground, Sams' had their own notation. With the correction you noted, then leaves some of the filament bypass caps in the set incorrectly grounded. I'm using the Wallaces' Motorola book which show C-18,24,27,28,33,79 and 80 to chassis ground. I used sams folder 71-12 to cross check. Zsuttle should probably use the riders schematic from the ETF. It would probably be more accurate.

I did some more checking today, it seems the ETF Riders schematic for the TS-4J is for the early version. I added a picture of the schematic for the late version power and filament supply.
