Slightly harder schematic to understand! Even the Sams isn't much better.

The TS-4 family created the B+ rail by using several stages between B++ and B- as a voltage divider. You know how some makes used the audio output as a voltage dropper instead of a resistor...Moto took it a step farther by using several tubes in series-parallel to make a voltage divider. Crazy but it worked.
