Where do I get...: microwave ovens

(Links generally point to photos)

The usual circuit of a microwave oven looks like this:

The cap C is charged to 3000V, so that at point (1), across D1, voltage varies between 0V and -6000V with mains frequency. The heating winding of Tr is isolated to withstand this voltage. I don't know the function of D2, maybe protection from over-voltage?

Useful components are:

WARNING: Never try to operate the magnetron outside the original case . Microwave radiation of this power is really dangerous, it will cook you.
