You will likely need to replace the regulator if the B+ is too high and the
caps are good. There is also a green ceramic in that PS that changes value,
IIRC. You might want to check.

Thanks Leonard,
I don't have the chassi handy but I'll lay odds
that C916 was probably one of the some 20
or more caps I replaced so maybe that problem
has already been fixed. I guess I'll try to power
up at least the SMPS on the bench and verify this.
