Finally, an update. Loading mechanism repaired, new drive belts fitted, plugged into mains, and initial test without a tape gave the result that the head drum revolves into place with the head spinning well, and the machine stays on (which I think is correct for that operation).
When tested with a tape, laced up well and correctly, but after a second or so, unlaced correctly and switched itself off. Green indicator light does not come on (bulb to be checked first), and will then consult the service manual, but if anyone has any suggestions I would be very interested to hear and try them.
