What is this?

Nordic · 29th June 2008, 07:02 PM

I remember this thing from when I was just a baby, it was a door stopper in my grandfather's house...

Its very heavy, and big, in the second photo you can see an a4 sheet (well most of it) for reference...

My guess is it is some kind of HV rectifier...

I'd like to know, just for novelty... its is realy pretty to look at, the copper area inside with those many little screws is pristenely clean, I guess it must be a vacuum... looks like it was made yesterday, that clean...

There is etching on the glass.  What does it read?  Is there anything printed or stamped on the metal?  What does it say?

A little data. please.  Five minimum electrical connections, could be a transmitting triode.

A very large forced air cooled transmitting tube. Its not a rectifier but probably the final for a radio/tv station.

I had one similar many years ago. It came from the transmitter in a LORAN-station.
IIRC the cooling fins are made of copper, you're right, it's heavy

Best regards

Magnetron from some radar?

Where you seeing 5 Poinz? To my eye it's case + 3, guessing a directly heated transmitting triode.

Doesn't look like a magnetron to me. Plus, there are too many leads. I'm voting for 'transmitting triode.'

I recognize this bottle since I used to buy and sell these things. I can tell you it is a type TBL6/6000 as seen in the number just below the pins. (enlarged & sharpened with MS photo editor) It's a forced air cooled triode with a 6000 watt plate dissipation rating made by Phillips and Amperex. From the look of the clean un-mottled copper, it still has a vacuum and may even be good if the filament isn't broken or shorted to the grid. These were used primarily for RF induction heating service.

Well, yer right, rdf,

I was looking at the picture wrong; there are three pins on the base, plus the metal, or potentially, heh) four.  My man above eyedeed the thing though, so there we are.  Non-audio buck-rogers triode.

Thanks Victor, those numbers are the same as printed at the top... so, you are clearly the winner!!!!

My grandfather was quite a genius at building stuff and also heavy into electronics...

I have now been able to look it up...

Power triode
Amp Factor (µ)=32
filament 12.6V
typical anode voltage 5100V
Typical Power Out 6900W!!!!!!!!!!!!!!!

I guess mine is the biggest!!!!!!!!
