is it the 13D1? Thats what Glenn sent me originally for the driver and he had the amp set to 25v

And the 25-volt version of the grey RCA and black Ken-Rad (25SN7GT) is labeled 1633.

The voltage switch only applies to the driver socket, so if you're using a 6sn7 or 6J5 w/ adapter you will want the voltage switch set to 6v.
If you're using 12sn7 or 12j5 w/ adapter the switch is set to 12v.
AFAIK there is only one tube out there that can be used for the 25v setting, but don't quote me on that.

The voltage switch has no impact on the rectifier socket(far left) or power sockets(rear 6) or the C3g sockets

There are at least 2, which I only know because you included 2 in the one you sold me! Both are amongst my favorites. https://www.radiomuseum.org/tubes/tube_cv423.html

Having the GEC A1834 and the GEC 6080, I am wondering if it is worthwhile to get the GEC A2293 triodes that must be used in pairs.
Has anybody been able to compare the A2293 to the other two GEC tubes?

@gibosi, maybe ?

I have never heard the A2293 triode. I would guess it is probably similar to the GEC tubes mentioned above, but not identical. And the only way to know for sure is to try them.

And then we have this http://www.r-type.org/exhib/aaa0224.htm...
Who has tried it? Any good?

The sticker is nice...

It never ends - there are only around 13,000 different types of tubes:

It would be easy for you to make room for that tube type. How many can you fit into one of your shoe boxes?

One question though; you know that tubes with flying leads are more difficult to catch, don't you?

Baby shoes or men's shoes?

LOL. Yeah, it definitely would take a lifetime. So many tubes and so little time!

For the newer GOTL owners, below is the Ked Rad 25 volt 1633 tube that @gibosi mentioned in an above post.
If you come across any of these, turn the switch on back of amp to 25 volt.
They have the staggered plates and they are very nice sounding, they bring the bass.
I think if you get any Ken Rad staggered plate tubes 6/12/25 volt you will be happy, they do not need to be the black glass.

Very nice tube, but very prone to developing noise issues too.

If any current Glenn owner would like to have a 5CU4 rectifier, there's one on eBay that I expect will go for not much money:
