In connection with my homebrew 6m 3-500Z amp that we discussed in an earlier
thread, I would like to try a test with a power supply from a different amp.
The homebrew amp's internal power supply has B+ and B- wires running from the
Harbach board. For the test, I'd like to remove just these 2 wires and connect
the B+ and B- to the external p/s. However, the internal p/s would remain
powered up to run the filaments, fan, and relay.
Is there any problem with this idea? In particularly, is it OK for the Harbach
board to be connected with no load?
The test would be far more difficult if I have to disconnect the internal p/s
