[amsat-bb] SSB Electronics MV 432 Preamp Info?

[Bill Bordy, NJ1H]

Does anyone have information on the SSB electronics MV 432 Preamp? The 
PC board is labled "MV 432 V" with country W- Germany.

Specifications, hookup or schematic would be appreciated. I already did 
a Google search and other than a photo of a "MV432 S" version. I could 
locate nothing. The "MV432 S" version PCB in the photo is not the same 
as the one I have acquired.
