OK if anybody knows this (Page 7): Nope, solid metal reflects the microwaves. They're not in the visual spectrum range of wavelengths.

Mine is much newer and plain white. I do ceramics too and if you have any ceramic dinnerware and it gets a crack, (even just a hairline), do not eat out of it or drink out of it. The slip that is under the paint has lead and it will leak as you use it. It is safe as long as there are no cracks.

Yep, and many microwave ovens don’t have a bleeder resistor accross the cap (all should), so it can maintain a HV charge for a long time. Take a hit from a 5-6KV charged cap, and there’s a good chance you won’t survive.

Both are inside the microwave, so I'm staying out.

Well guess what! Before I saw all that, I went in there and took the magnetron out and cleaned it. It didn't kill me. Well, if it did, don't tell me.

Many high voltage equipment with large capacitors do have bleeder resistors but guess what? These resistors tend to be broken often. The equipment would work just fine but doesn't discharge the capacitors when you disconnect the power.

Note that old CRT based TVs also used high voltage. The newer flat screen TVs are solid state and use moderate voltages.

My father used to repair our old, broken TV, and I remember something like a "Hot Box" inside the set. There was a cage around several tubes.

Just like the cap on the fly-back transformer in a tube TV for the picture tube anode voltage.

Well those flyback anode voltage is higher around 15kV. The magnetron power supply is only around 2kV but of course it's capable of much higher current than the picture tube anode voltage.

Yes indeed. I have a home built 4KV 1Amp HV supply for my HF linear amp. Not only do I have a 200W bleeder, but also a meter with multiplier BEFORE the bleeder so I know the cap is discharged. Even then, when I remove the (interlocked) top cover, I short everything with a grounding stick. You typically don’t get second chances with HV like this.

It seems that when more than one "gadget" malfunctions off the same electrical line, it's the line that's at fault. Maybe it can't handle the amount of power needed to run the devices. I know nothing about this. Just guessing. Your electrician neighbor should be consulted before you plug anything else into the outlet.

Thanks Vicki. I sent him a message and he says he will come over and take a look. The fun part is catching each other at home.
I think you are right. I have nothing plugged in there now and won't until it's fixed.
