Aloha,
Electric weed eaters have some nice bridge rectifiers.
There is a surplus electronics warehouse in the San Fernando Valley called Apex, I think. Anyone live near the valley?
This place has parts and components stacked to the ceiling, and the prices are CHEEEP, some things are sold by the pound. I have never been there, but my brother went there for me and picked up some goodys. There is a lot of military and industrial surplus too. It's a lot of hunting though, expect to spend the good part of a day, as there is only help at the counter, and stuff is scattered all over. I am tempted to take a trip over just to go there.
Bill
