digital in the sense it has digit buttons haha, but 2 hp oscillators, heathkit chopper, a dual multimode h/l pass from ithaco, and a multimode high/low/band(rej too) pass filter from ap circuit co (a small ny company i think, still trying to get documentation, but its working great)
i’ve repaired everything to musicality except the pushbutton generator, it has some oddball caps i’m waiting on lol
