Noah's Ark for electron tubes

[Gold_xyz]

Hi,
If You had to save ten types of Electron tubes of whole world production
Which would you bring inside the ark?
Why?

tnx ! 😀

 

[Burnedfingers]

I would bring a 12AU7 so we could all remember what true junk is

 

[Fuling]

AD1

 

[sharpi31]

I'd also bring a 12AU7, just to annoy burnedfingers.

(and also because Bruce's grounded grid preamp is so good!)

6ca4, 6au6, 6aq5, 12at7, 832, 12ax7. Mostly because after the flood, assuming I can find a working power outlet, I'd hate to have to rebuild my amps to work with the tubes that someone else had the forethought to bring.

5R4, 6AQ5, 6AU6, 6BA6, 6DC6, 6EA8, 6L6, 12AT7, 6146, 6550.

Because you can build about anything from DC up to about 175MHz from those types.

If I could go to eleven, I'd include 3-500, 4-1000, or something in that class.

enough tubes to keep my current (and future) gear running:

5AR4
5U4

6550
EL156

5687
EF86
5751
12BH7

I'll throw in the 300B and 2A3 since they are such classics.

Can we change our mind? I want to pull 6AQ5 from my list, and add 6GK6 in its place.

Don't you have to have two of each type so they can reproduce?

I tried to mate an 807 with another 807 and they had conjoined twins. I named the twins 829.
