I ran across an old Electro-Music PS-10 B+ supply in a Hammond BCV. Anyone seen one of these before? It's on the primitive side, just a half-wave rectifier and two capacitor sections with a 1k resistor in-between. Ripple reduction is not great with 47mV ripple at the preamp B+ terminals. No regulation, of course.
This organ also has a two-tube Electro-Music Percussion unit in it, but the power to it was disconnected and tied off by a previous tech for unknown reasons.
