50 silicon diodes and your good to go. I have seen similar done in a machine I sometimes work on. They replaced one with a PCB full of silicon diodes. It drives a pair of these delivering 10kw.

I have seen that wile working with these. It is normal for them as we run them at up to 200% of their continuous rating in bursts. I have been told it from xrays exiting left over junk on the glass.

I know where >>>/biz/ is and its not here.

You won't get anything from us cheaper than the internet. We are handy for people who walk in and walk out with parts but we don't make money selling below cost. Also do electronic repairs and sometimes build custom stuff for people. Have fixed stuff from grandma's torch with 2 D cells to 10kw RF stuff containing a few of pic related.

If you are talking devices that run mismatched often then yes. 50kw sold state transmitters with hot plugable output modules are a thing these days. That said I still work on equipment designed for regular mismatchs that still runs valves. We also run them at 200% of their rating but not continuously.

That is small in comparison to some.

Do you have a circuit diagram for that picture?

Not a ham but from vk3. Have listened to them on and off for years. Often listen to 160 metres.

I sometimes work with dem big bottles at work (pic related).
