AB Systems Precedent 900 parts deck

Audio Proz Inv #: 49836

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.
