I have what I believe to be a Gonset Prototype, that was never put into
production.

It appears to be 6M transceiver of the kind to have separate receiver, and
separate transmitter.

It has a built in DC vibrator supply. It looks like it also worked from an
external AC supply (see the 12 contact Jones plug jack on the back).
However, maybe it is a combination DC and AC supply. If so, then the same
two SS diodes work as rectiifiers in both operations.

I don't have the schematic. However the component chassis may have some
relationship to chassis that were part of other units. I am trying to
figure out the Jones plug connections; here again, maybe there is some
similarity to some actual production models.

I have looked at about 12 - 15 schematics. I saw no separate AC supply.
Some had combination AC and DC supplies, and they also used 12 contact Jones
plugs (as my set does). So maybe I'm wrong, maybe this has a combination
supply. In each
schematic that showed the wiring for a jones plug, the 110 V AC went to pins
5 & 8. If I did that, the (working side of the) switch on the front would
short them. The toggle switch on the front is a 2 pole single throw. One
side of the toggle swirch is not working.

The best I can figure out on the Jones plug is:
1 To the non-working side of the toggle switch.
2 Pin number 2 on the 4 prong vibrator
3 Pin number 4 on the vibrator
4 No connection
5 To the working side of the switch
6 To the transformer
7 Chassis ground
8 Other terminal of the working switch
9 Transformer
10 Chassis ground
11 Other terminal of the non-working side of the switch
12 Pin 1 of the vibrator

And here are some pics:

What I am looking for is either an expert on Gonset, or maybe some one who
worked at Gonset who can give me some more info than I have admitted to
above.
