Thanks Brian. It would have been even nicer if I hadn't have cut the 
primary wires on the 18V transformer so short I had to add an extra 
terminal block to extend them. Doh!

The photo doesn't show the finished unit. I have since added the 
Oberheim Interface circuitry back and fitted a nice new DB37 connector 
to the rear. I also upgraded the power supply wiring to the motherboard 
and CPU board from the PSU. The wires that Oberheim used were very thin 
creating a very noisy 25mV drop across the ones to the CPU board. Upping 
them to 24/0.2 dropped that to less than 3mV which substantially reduced 
the noise on the 0V on the CPU board. Did it make an audible difference? 
Who knows, but it makes me happier.
