I doubt it, as my old 1988 Courier HST uses a standard (large) 5-pin DIN
plug on its secondary power lead, but there are still only 2 pins being
used, the same 2 as per the later Austel models.

No, the old ones are the same, and only the plug size has changed.  Before
the new style concentric connector was introduced, the DIN plugs had
17-0-17 VAC (centre-tapped) supplied to them, regardless of their size.
