OK.

First let me tell you an old Soviet joke my mom the physician told me long time ago.

In a med school, in the anathomical theater, the anatomy professor standing near a corpse, which is in not so good a condition, addresses his students:
"A physician should not be squeamish."
With these words, he pokes the dead body with his finger, which finger goes right through, then pulls it back and licks it. Then he says:
"OK, who's going to repit this?"
A young fellow, emboldened by this, comes forward and repeats the same, using his index finger.

The professor then praises the young man, and adds:
"As I have told you many times before, a physician should also be very observant."
He shows them his hand:
"I poke the corpse with this" - he produces his index finger, - "but I liked this" - and he shows them his middle finger.



Why have I told you this?
I've been doing all this search because I thought I needed an adaptor from UV base to the UX base.
What I totally missed was the fact that:
- The UX base DOES have the bayonet locking pin on its side, and
- the distance from that pin to the tips of the base pins is the same as in the UV base.

So, the UX tubes go and lock in those UV sockets just fine.

The question is withdrawn.

The radio restorer should be observant

To my defence: them black bases totally masked the presense of the locator pin.
I tested 6 tubes in my Hickok 600A, and never noticed them.
