sounds like old CVS-50D (D = two rang switch and S is 3 range) and the blue
socket is for audio or Mk 4 director OR CNAV - all about 20 to 30 years old
I would say. Ian McPhee

Hi,

At the local club there is a number of older Electronic
Cambridge Varios hanging round.
Some are supposed to be working but they have been
pulled out and the wiring harness lost.
They have a small multipin blue socket on the back,
and a plain face with no switches or knobs.
The model numbers appear to have been written on with
pen and have faded on them all.
Does anyone know where I can find wiring Data for these
units ?


Thanks
