Sourceing parts is quite an experience. First I recieved the power supply electrolytics and even though I measured with a caliper; lo and behold the Nichicons I ordered happen to have a little lip on the lead side, which just conflicts with spacing on the board. The caps are squeezed in but now the power transistor is too close to the lip of the caps and so must be set at an angle. The two Riken resistors are way too big for the board so had to moto-tool some edges. No place for a heat sink for the transistor so had to get creative and bend around the electrolytics. This is a learning process. The best advice I got so far is to look at parts sourceing as a creative and artfull job. Even so I keep my three pound hammer handy.
Anyway the power supply is done. I just have to don my asbestus suit and fire it up. I have lots of extra parts now also.
