Parts unit sold as is. Unit has been partially repaired but has a bad transformer (L01-1611-05). Definitely repairable but this part must be replaced. Circuit boards were repaired at one time.

Parts for repair. 380004400 rev 8. AMP board only, intact low use and tested with switch. Output transistors listed 2SD746A, 2SB608A $28 each. 2 pieces or more to purchase 22 each.
This is a complete Precedent Series 900, but one channel has failed at low level circuits. Very good cosmetic condition, very good electronic condition overall with no burnt parts. Buy the whole amp as is for $140 and shipping will be expensive, or but just the remaining perfect condition channel board (502-622) for $100. An experienced hobbyist could repair channel 2 with a basic parts kit.
