Are old high voltage components from microwave ovens useful, or should
I chuck them out in the trash?

I have several transformers that look like they are good for quite a
few watts of power, some of the high voltage diodes and several
blowers. I've been saving them.

Can they be used for power supplies for rf transmitters? Are the
blowers any good for cooling large tubes in transmitters?

Of course you can use the diodes and the capacitors ;-)
There are some articles on th Internet about converting the transformer for
a spot welder.
A also saw an article on using the magnetron as a PLL like amplifier to put
out 1kw at 13 cm. I can forward the link if you want.
