My approach would be to build a basic 12v. 3-amp. linear PSU using a suitable mains transformer. If a regulator cct. is needed, a simple design based on a 2N3055 should be sufficient. A generously-rated circuit and thermal design should give a PSU which will last for years without failure. What's your salvage stock like for the necessary bits?
