The AM904A Vintage Module is a Behringer 904A low pass filter professionally upgraded with the AMSynths Daughter Board to deliver the original 1968 version from the Moog Modular synthesizer.

 The upgrade consists of a populated Daughter Board PCB that is attached to the rear of the Behringer PCB. The new PCB is populated with high quality polypropylene capacitors and header pins and uses the existing Behringer Euro Rack power connector.

The upgraded 904A delivers a faithful reproduction of the 1968 Moog filter with the correct lower capacitor values and high quality sound. The Behringer warranty is voided by the upgrade, but AMSynths provide a  two year warramty in its place.

The module come is a new box as it is deeper at 35mm, and comes with power cable and M3 mounting screws and washers.
