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.

ADA Microtube 200

Audio Proz Inv #: 43733

Power amp. Parts unit. Contact us about repair, parts, or replacement.


Vince has noted that although this was a clever and interesting product,
the problem is this unit suffered some very simple but problematic design flaws back then and Vince has always modified them to be reliable.

*This is not a recommended product unless someone like Vince knows how to resolve these issues*

We have better options if you would like to call.
