You need to look at the manual for the TM506.toggle quoted messageShow quoted text
3A, 3B, 4A, 4B are all the return for the 11.5 volts. It's done that way to share the load on the pins, not an uncommon situation for a design.
That's why the 11.5 volt + leads are paralleled (pin wise), and the 33 volt power supply.
I do that lots, it tends to save pins and wires. It lowers the resistance to the other board.

All the voltages you guys told me to check, check out fine, although a bit higher than expected.
