Just before opening it up, I noticed the phantom button, in on position.
Repowering again 48V on and switching off, after 5 sec or so the
intrusion noise went. Testing for 48V , something tries to establish on
the mic line but drops to 0V over about 5 seconds. So the 48V subcircuit
needs exploring



It is worth bearing in mind that not all units supplying phantom power do so
at 48v.

IIRC the Dynacord Powermate 1000 Mk1, for instance, uses something like 24v.
