Spare tube help

[Herbie the Rad Dorklift]

Hello guys, as I stated in other posts I just bought a new Mark IV.

Now, I'm all professional about gigs nowadays, with my little carrycase of spares and whatnot. Except I'm missing one thing, spare tubes!

Any info with which tubes to buy, and where to buy them (I'm in the UK). Also how to store them.

Cheers guys, I'm a valve n00b, so I know nothing about the tubes themselves.

My Mark IV is all stock if that helps.

Cheers!

Basically you've got to store and transport tubes as if you're carrying a box of light bulbs. Lots of padding in a un-crush-able container.
By the way, most of the tube manufacturers (Philips, Sylvania, etc.) started out as, and still are, makers of light bulbs.
For those expensive Mullard 12AX7s, I like those plastic screw-top urine sample cups you get at the doctor. No one steals urine samples.
