Problem solved! There were 2 miswires in the B+ supply. The connections to the field coil were "swapped" resulting in nearly the entire secondary load being connected to the input side of the FC, instead of the output side of the FC! Partly due to 2 identical capacitors used in the secondary PS filter (C61 and C58).

Sigh, it's always where you least expect to find the problem...
