Anyone ever use a power supply from a microwave oven to run a linear amp? I am starting work with one of my Elmers on an amp project and he has most of the stuff for the project except for the power supply. One of the things we are hoping to do is use inexpensive or salvaged parts to keep the cost as low as possible. Microwave ovens are cheap or free and can be found everywhere. He remembers reading about using microwave oven power supplies for such applications awhile back, but we have been unable to find any information in our search. Have any of you guys used such a power supply in an amplifier?
