Good morning everyone,
I'm working on racking an RCA BA-31 module, I opted not to use the built in power supply but instead used a Five Fish PSU.
I Connected +30v to point B and -30v to point P.
When I fired up the unit it worked for a minute but then R17 started smoking and burned up.
Is that the proper hook up? Looking at the schematic I don't really understand where ground is on the built in PSU.
Thanks!
