Hello Bryan, I've got a Rappaport Amp 1 in perfect working order. I rebuilt the outputs with hand-matched motorola OEM transistors and rebiased the unit about 5 years ago and it has about 30-40 hours on it. Just finding the proper output transistors was a complicated matter. Cosmetically it's in pretty good shape for its age and i would consider selling it for the right price considering its rarity.
