I guess what you have learnt by building and testing the bench power supply and the pleasure of getting to work far outweighs the small cost. IMHO it is the best way to learn, there are too many theoretical engineers on the Forums, I think some of them should have been Accountants... [thinking about it, I suspect some of them are.!] Last edited: Jan 13, 2011
