Martin Audio Varispeed III schematic?

[fazeka]

Hi,

I have a Martin Audio Varispeed III that I picked up recently and am looking for a manual and/or schematics for it.

I want to use it with my 3M M56 and Ampex AG350s.

I have the Burndy connector and the Amphenol plugs to interface to the 3M capstan motor but need a schematic to determine how to wire up the cable.

Also planning to acquire the Jones 306 connectors for the AG350 assuming a similar setup (that is, the MA Varispeed in series with the capstan motor).

Anyone have any Martin Audio documentation lying around they can share?

Thanks,
Chris

I have the same question. Have an Ampex 440B here and have located a Martin Audio unit, but lack cabling and need a scheme to make one. Any info would be  much appreciated!!

Best

Tim
