Hi guys.

Here I have some stuff for sale. Details below.

4-1000A Vacuum tube - asking 100$ OBO

Last year I did a trade with another member for a bunch of VTTC stuff. Unfortunately I don't know anything about making Tesla coils. I recently offered to pay anyone to build me one with my stuff with no luck. So I decided I'm going to give up on a super awesome VTTC.

I have a 4-1000A Vac tube. Tube is in EXCELLENT condition. I've certainly never used it.

If you are into Vacuum tubes you should know what this is.

I'm asking 110$ shipped OBO. I accept trades as well.

Thanks!
Jeff

Re: Sell/Trade 1KW Vac Tube.

Heh. They seem to getting more attention than my actual sale item! Maybe I should look into selling those too? :thinking:

Edit:

Fun fact: 4-1000A vacuum tubes contain a small amount of Thorium.

Re: Sell/Trade 1KW Vac Tube.

Nice looking tube although some discoloration on a couple fins in picture #3.

Has it been tested and checked? Is it used or unused?

Have you tried putting it on a shortwave enthusiast site or eBay being it is a shortwave transmitter tube? There are guys out there that still build and use them.

Re: Sell/Trade 1KW Vac Tube.

I assume the discoloration you see on the fins is the yellow lines. If so those are not actually on the tube
Its a camera artifact.

I'm not sure its been tested or checked but I would be willing to guarantee it works or the buyers money back. I don't know anything much about the tube itself besides the information passed to me. I could maybe test it to the buyers instruction.

As I said in the OP. I got it with the intention of making a VTTC. I just don't know much about building one. I wouldn't have the slightest idea where to find a short wave enthusiast forum. Rather not deal with eBay XD

I really appreciate the help encap. I really have no idea where I could sell this besides here haha.

Re: Sell/Trade 1KW Vac Tube.

Oh OK just artifacts not discolored squiggles on two of the fins.

To use/ to be a functioning tube, you need a special socket for it that houses a fan and the glass chimney that goes over it that directs the air cooling it--not so easy to find.

Is a pretty specialized thing for it to be used for other than just as a very cool looking big tube on display, which it is.

Probably eBay is best bet.

In any case good luck with it.

I've lowered the price for this ALOT. Apparently you can get these on eBay for about 100$. Mine looks better than most on ebay. Hopefully price is good now.

Re: Sell/Trade 1KW Vac Tube.

You can tell that the tube has been used a bit by the color of the glass. Most types of vacuum tubes produce x-rays by way of bremsstrahlung (braking) radiation. When some of the accelerated electrons flowing through the tube get scattered and strike the glass envelope and/or other parts of the tube, they lose their energy via interaction with the atoms in whatever material they encounter (they slow down) and in the process an x-ray photon is released. Over time, this x-ray radiation causes silicate glass to turn brownish. The same thing happens with medical x-ray tubes.

Re: Sell/Trade 1KW Vac Tube.

If you want to help your sale of the tube you could do a continuity check on the heater element and assure prospective buyers that is is intact.

And yes I can tell it's a used tube by the look of it, brown glass, but it dose look very good.

So did I see the supper caps are 3000 farad @ 2.75 volts ?

are they for sale and if so how much ?
