I was afraid this might be the case.
: Your best chance is if anyone has the channel selector board from this : or a similar model. If you have two banks of the switches, with care and : a delicate touch with small mechanical assemblies you should be able to : rebuild one working set. What damage has there been to the original : set? They *may* be fixable.
The interlocking mechanism is driven by a bar which runs horizontally underneath the switches. I've not yet striped it down completely but the bar has six tiny vertically mounted posts which reach up into the switches to give the interlocking action. Some of these posts appear to be damaged.
Regards Tom.
