[MRCA] DY-105B testing questions

[Jason WA6BBQ]

Hi, I’d like to test and verify that my DY-105B is putting out correct and
safe voltages before attempting to power up my GRC-9 with it.

I can trick the dynamotor into starting and can see appropriate HV, but all
the low voltage circuits apparently want to see a load, and that load
appears to be integral to regulation.

Open circuit, the 1.5v supply shows 24 volts… Not confidence inspiring.
Blowing up one 3v flashlight bulb is one too many.

Has anyone come up with test loads that would cause the thing to operate as
expected?

Thanks,
Jason WA6BBQ.
