I'm assembling power supplies for a tube amp project using two separate transformers. The main trans will supply the B+ circuit and the tube-heater circuit. The second trans will power the driver board (115v) I plan to place all three circuits on the same piece of pro board. The B+ and heater circuits will share a common ground bus.
Question: Is there anything wrong with grounding the driver circuit to the same bus as the other two?
