That sounds like the one. IIRC the very first model only had 2 sockets --
the extension speaker socket came later.

Yes. You could also feed in 7.5V through one of the sockets -- it was a
'240 degree' DIN socket used for external power, remote control, and

'tube' to carry the microphone.

from the appropriate year of 'Radio and Television Servicing', although
sometimes oen was folded up inside the machine anyway.
