I have a Gilford 2600 UV/Vis spectrophotometer circa 1981 which was
rescued from the dump. From what I can gather from a for sale image
on the web I have all the bits, however I am comfused about the power
supply system. There are two power supplies present, 1 in the main
spectro unit and 1 in the cell changer. There were patch cords with my
unit but the trouble is the gender of the wide d-connector which plugs
into the photometer unit is wrong for the corresponding plugs on the
main unit (labelled digital in and -out). This suggests to me that the
power supply for both the photometer and lamps for that matter may be
a separate module. Can anyone confirm this or if incorrect guide me on
the connection configuration ie. what plugs into what. I can't just
test the unit as I've had it stored for quite a few years and a number
of the common logic /op amp chips on the circuit boards have corroded
thus breaking the connection and so the unit is currently
disfunctional. It was OK when stored but before hunting down all the
damaged chips I'd like to determine if I will still be short a power
supply. Thanks in advance.
Pictures of a Gilford 2600 can be found at this site.

My early career was as a technician in a chemistry lab. I'm not
familiar with this unit, but worked with equivalent (older) units from
other manufacturers. In general these consisted of the main
spectrographic unit and a number of additional units - light sources,
detectors, sample holders, etc. These represented various options
which varied by application. In many cases the power supply for the
light source was a separate unit. A sample changer might also have
it's own source.
