JMP loop

[angushung]

When adding a loop to a JMP, where does the 30v come from that powers it? I know the "in" and "out" hookups and where they belong but im confused a bit on the power issue. 2nd rc filter? I've only messed with a Steve Miller loop and I recall it getting power from B+ at phase inverter

30v? for what, an op-amp? Maybe use the bias supply.
