2001 A TUBE ODDITY

did the drawings.

looks spacy

I like it.

In anodised aluminium...

The socket and all the electronics

Finally got the socket done.

It weighs about half a kilo.

That's one pound for you guys at the other side.

Including the copper contacts.

Machined out of a solid copper bar.

Just to imagine the size, I put my mobile next to it.

It is NOT a toy or scaled version.

No.

And the electronics come down to this.

Almost nothing.

11 components per side.

That's it.

The ultimo penultimo diagram

The cathode follower.

Now, that was easy....

As promised; THE DIAGRAM......

only 10 components left...

Does it get better than this?

Well, things are never as they seam

Got the interstage!

It sounds funny...

Measured with the scope...

Not so nice.

It has a nasty dip in it.

Tried about everything.

And then some more.

Back to the drawing board.

Asked Wim for help.

Brilliant idea!!

The Cathode follower.

No interstage, no couple capacitor.

Back to DC.

Ok, the power is down a bit.

Only about 20W left.

Still more then enough!!
