I've mentioned this before, but it bears repeating.
If you are having trouble with an old school linear power supply, in
many cases you can replace the TO-220 PNP pass transistor *and* the
reguatlor circuit (based on a 723 or whatever) with a modern integrated
regulator in TO-220 such as an LT1581. Strip the regular board of
everything except for the the input and output caps (if they are still
good) and wire up a pair of resistors to set the voltage. Add a couple
of jumpers to complete the circuit. And then you are good to go.
