This is quite likely - I've noticed that several other modules do this, but
since these are generally processing audio, rather than CV signals, it won't
help your current problem!

Yes, the electronics are quite straightforward - there is very little to an
A-175! One problem with trying to put it into a 'cable' will be supplying
power to it. It would be relatively easy to make up a longer than normal
power ribbon (I've made up several - Maplin in UK sell the necessary bits,
I'll check out part nos. if interested), attach it to an unused slot on the
busboard and then feed it out of the case at some convenient point in order
to drive a stand-alone 175, as Joe suggests.
