Op Amp Regulated Supply for 60 Hz that works up to a decently high amount of power. Op Amp is wired so that it effectively has a gain of 6. This is fed into a push pull emitter follower so that power is not limited by the op-amp. Frequency response of the feedback was tweaked slightly in order for stability with reactive loads.
10 nH inductor placed in series in order to mimic a reactive load
