The Bi-Motes that I have are M5233 ( PCB) these are the ones with the 5879's and 12AU7..

There may have also been another versions with EF86's..
The Bi-Mote was the Program Amp section of a Gatesway and or a Yard... ( with a pair of Davins , a Power supply and Enclosure)

As you can see this is the same PCB that is used in the Dynamote, Bimote, Yard and Gatesway...

The Yard changed from 5879 tubes to EF86 in the mid 60's I believe that I have  Bimotes with that same board .. M6142..

I have collected many Program Amp sections of the Yard and the Gatesway for the very purpose of DIY building of "UniMotes"

If  sharing (re-posting)  my posted schematics please just acknowledge where they came from or point to my URL.

Thanks and good luck
