Thanks for the suggestions. The power supply is now fixed. The
problem was one of the transistors controlling the big series power
transistor. The faulty transistor was part of a feedback loop
comparing the output voltage to some set reference.

The suggestion that helped the most was to order the manual on ebay.



Glad you sorted it, and we were able to be of some help to you
