Default microwave transformer for PSu

will this work? my uncle was throwing his microwave away, so i salvaged a few things out of it.

I was thinking about using the transformer out of it, so i don't have to purchase another one for an amp.

What are the normal operating voltages for a magnetometer or whatever you call the thing that emits the microwaves?

Thanks for any feedback

It's called an mot or microwave oven transformer and I belive a common output voltage for it would be in the 3~5KV range and could be as much as 1kva in a large oven.

The Magnetron is what is used to create the high frequency microwaves and is more or less a vaccum tube diode.

You could rewrap the transformers secondary to a more suitable split voltage.

...or make a nice choke, like Circlotron did.

As Easyamp pointed out, you usually have several kV at one
of the secondaries of such transformers, so don't even try to
plug it in and measure the voltage.

If you plan to rewind it for some suitable voltage, then I
suggest you start by winding off all the secondaries and then
try with a few turns of wire to find out the Volts/turn ratio.

okie, so using it as it is currently is out of the question. Something more to do in my free time though. This'll be fun.
