Hi Stu again,
Oh boy; it's been a few years since I did one of these.

I think you will find that if you have a careful look at the frame connections on the coils, you will see one tag that is not connected with the windings, and is connected to the FOT. This will be one end of the thermistor.
It should be easy to trace where the other end comes out on the scan coil board.

The 950 Mk1 had a half wave eht 'tray' [Red plastic jellypot]

The Mk2 had a tripler.[Grey or white jellypot]

They are virtually the same chassis other than this.

Regards John.
