Hi All,

Can someone provide me with a scan or a photo of the circuit schematic for the pre-amp board for a DeltaPlus?  Details below.  Thanks in advance, Jason

Delta Plus
 Instrument built Jan 24, 2002
Three collectors (this one uses cups 2,3,4)
Pre-Amp board probably C4536103830-02 rev1 (date 30 March 1995) - very hard to read
housed in an industrial looking rectangular aluminum box

(Not the Octal pre-amp board
housed in a shiny expensive looking round aluminum box
I have this schematic)
