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.

Win W5JAG

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