Hey Dave,
A customer just gave me an Ampex 350 module to "modify" to be a mic preamp !
Normally there no mods required, just switch to Mic and monitor output, but this
unit has a module from VIF International plugged into the V405 socket. I can't find a
readable schematic for the 350, so I don't know if this is a "replacement" input transformer, or some other mod. Do you have a readable copy of the 350 audio schematic, or any knowledge of the VIF International #1002-350 module ?

Thanks a lot,
