From your pic it looks as if just one small greencap capacitor
has been used to replace a polystyrene cap.
The rest looks OK - some resistors are changed to metal film (small blue ones).
And the RCA big transistor replaces a Motorola one - easy change if needed.
No real problems. If you were able to recap them, you could change the greencap
and big transistor pretty easy.
So, do you have a rack for these ? And a +24VDC 250mA wall wart for testing.
While you are organising that, and I'm sure you will get the know-how to wire the rest.
More pics - say of the whole module, then detail on the pcb connector and the rear
connector so see just what wiring is there.
Between you, your tech and the forum you will get there!
