I didn't realise there were such cheap kits available. I'm not averse to cheating either. I'm not even registered on ebay where I expect most of these things are sold. Do you have a link?
I think you're right about bulk replacement. It might lack precision but it gives the right answer quickly.
Believe it or not I've never actually serviced a switchmode PSU before. Not really designed one either unelss you count the National "Simple Switchers". Actually that's not strictly true. I did once build a flyback converter to supply voltages up to 900V or so for a vidicon camera that I was modifying. Stabilising was a long string of zeners which also gave me the intermediate voltages needed.
