BA-71A Schematic.
JLM Modified BA-71A Schematic. Moving R17 out of the -30v power feed and replacing with a link now makes this the 0v ground common.
Adding the R17 in series with the +30v rail makes this a positive powered module. Allowing it to be powered easily by our Power Plant kit or 48v SMPS + TREX kit.
Both Power Plant kit or 48v SMPS + TREX kit options will give +30v to run the module and +48v for phantom power.
