Cluster Gauge from 1987 J model and transducer amps

[jastu23]

I had this cluster gauge removed when i upgraded to my EI primary instruments.  Unfortunately, the oil pressure does not work properly (it is intermittent), and I had it diagnosed as the amplifier that was used in this model mooney.  I was planning an upgrade, so never did the repair.  All other gauges are working, however.  I have no idea what, if any value this may have to anyone, but thought this would be the best place to try.  I'll entertain all offers.  

I also removed many other items which I'll be listing elsewhere, but message me if you're interested.  They include a UBG-16 (4 cylinder), KLN-90B GPS, KT 76A transponder, and KMA24 audio panel.
