[R-390] One-Fuser to Three-Fuser

[Tom Warren]

 Gentle folks,
 
 Does anyone have detailed instructions for converting a one-fuser 390A to
a three-fuser?  By that I mean essentially a wire-by-wire set of
instructions.  I can certainly read the wiring diagrams and figure it out,
but  hey, if someone has been here before and put out a set of directions,
I will forever praise (well, at least for two weeks) his name.
 
 I'm converting a one-fuser Motorola '56 mainframe to a three-fuser. I see
that Motorola told a little white one also in that the Y2K manual says
that after SN 2XXX (it's in the manual and I didn't write down the number)
they all became three-fusers (that is, on the '56 contract plus all of the
'58 contract).  But my mainframe SN is 32XX (again number not written
down) and it's about as one-fuser as it comes. My SN 32XX mainframe has
other miscellaneous holes for extra coax connectors associated with the
outboard frequency stabilization modifications done to this particular
390A.

I've actually disassembled the entire Motorola mainframe to its
components.  I have a spare three-fuser back panel, so I won't have to
drill those funny D-shaped holes. I also have better side panels and other
pieces than in the original Motorola mainframe. So I'm going to reassemble
with the best parts I have.

Many thanks for any potential help.
