Very cool!!

Very small cramped room so I couldnt get a good shot of the whole thing.

Its still a pretty cool device. :3

intresting (and they say radio isnt dangerous! )

yeah it is.

How much heater current that that bugger pull?

Forgot the specs but a lot. Ill look next time I am out at the tower.

The 'Chicken Stick' is your friend.

We call it the jesus stick.

20kW ? Biil for electricity will be horrendous !
What is destination of this "pretty cool device" ?

Well... the supply to the rotophase is 200 amps so yeah probably pretty hefty. As for the location its in the middle of a cowpasture in the middle of nowhere.

Very neat, I love seeing RF equipment - Ham Radio guy here.

Working on that license too.

I know very well about such high performance Tubes. I woked with ones for CO2 Laser Generators called Resonators. They work with 10kV on a Load of 14 to 20 kW´s at 13,xxx Mhz Frequency. This tubes are Pre-heated with a 5V DC Coil at 180-200Amps. And also inhoused in a Radio frequency sealed Housing.

Ill bet the harmonics on that could get intresting.

I've got an 862-UV. 20KV at 12.5 amps. It's about 5 feet tall, and water cooled:

A pair took 500KW, CCS.

Impressive. This is aircooled by a 3 phase squirrel cage blower at about 100mph. It has a windvane on it.. if the airflow over the tube drops even SLIGHTLY it shuts the tube down.

Biggest that I ever worked with hot was a water cooled 90KW 450KHz induction heater. In some of our experiments we would get 100+KV RF transients - it had an X-ray warning sign.

Ill bet it did.

Whoa that's a scary sucker!

They're always impressive, it's good to see vapor state still being loved.

I'm trying to make sure a big mercury arc rectifier that's in a local museum finds an appropriate home. The museum's closed down and I'd hate to see it broken up just for the sake of the value of the mercury. I've always wanted to see a big rectifier like this in action, but I can't think where I could do that nowdays.

Trouble with the old tube stuff is getting the power for them. A lot of them require 3 phase which you cant get at home (or you can but the power company will want to know why) or like we do and use a rotophase.
