Juno 106 noisy chorus repair

I was able to repair crackling on the Juno 106 chorus by replacing all the tiny transistors (npn and pnp) on the jack/chorus board, as well as recalibrating the chorus section. The crackling occurred when bass heavy tones (especially chords) were played.

Some of the replacement transistors, although excellent substitutions electrically, needed to have their legs twisted since the pinouts were different.
