  Anybody ever gone on a plane ride with their STAX? Not wearing them on the plane itself, just putting them in a carry-on.
I'm considering bringing my SR-202s back home over winter break, but I don't know if the cardboard and styrofoam box would fare very well.

they would fare fine if you carry them on.  I'd never check them.

I guess that a second, bigger box would be a good choice, as the cardboard one doesn't offer a lot of protection. Those travel cases for music equipment would be a very good choice in my opinion! But I'm a bit of a perfectionist anyway...

A STAX within a styrofoam case, within a cardboard box, within a bag, within a layer if bubble wrap, within a larger box, within a backpack, within a carry-on suitcase should be fine.

Oh no, no way in heck would I ever check them.

Do you have any recommendations for cases to use? I looked a bit on Amazon at pelican cases but didn't see anything that looked like it would be big enough without costing $100 or so.

Of course that would work, but I want room for slightly more important things in my carry-on, like clothes.

That's the problem... quality cases that are big enough cost quite something. Maybe you could use the case for something else in the future?

I would put it like the same way if I was posting it, putting it in a thick plastic bag (that can be filled with air a a bit and then sealed, I don't know when I got one but it fits the Lambda perfectly) and some bubble wrapper around it one or two times for good measure should do the job just fine and does not take up that much space either. Or the original box is fine as well, plenty of options.
Maybe you should take them wearing around your neck but the headband wouldn't like that very much, so best is to put them on. I wonder if a Sigma would past security this way

  A triode has two systems inside the tube. The numbers should be as close as possible, that means that the two systems emit electrons equally strong. A higher number usually indicates that the tube is in a good shape. Depending on which type of tube and tube testing device there is a number that is equal to 100% quality (=full power).

 
An excellent explanation, +1.

more like the reverse:
 
The tube has two triodes in it.
the number indicates gain, so if the numbers are the same or similar then the gain is closely matched.

Thanks for the correction!

Triode = 2
 
The values resulted from testing tubes depends on the "tube tester" you use, either a Hickok, Amplitrex, SWL etc all have different readings for the tubes you're testing. There are 3 things you can test a tube based on it's plate resistance, plate current and transconductance. Most ebay sellers usually test the latter two being easier to measure and follow. Generally a NOS tube would be 2600 mho or 100, i.e unused but anything near these values is better or in other words the higher the value the better. When you buy "matched" set tubes, they are based on these values matching as closely to each other as possible as well as measurements on a curve tracer. 
To answer the original question the value is mu/gm.  
This is what I know but theres more stuff online you can read about.

Triode, by definition, DOES NOT = 2.
Many power triodes only have one triode in the tube envelope.
 
The tube envelopes normally contain 2 triodes in small signal devices, but there is no law or rules stating that they need to have 2 in them.
A triode is a 3 point device, grid, anode and cathode.
Theoretically, you could have three triodes in an 11 pin tube, pin 10 and 11 would be heater connections.  
 
 
The xx/xx number they were referring to is typically transconductance, i.e. gain: how much output current do you get referred to input voltage, expressed as "mho":   or amps per volt.

You're right. It's a bit of a strange statement, as "tri" indicates there are 3 parts. If it was about the number two, then we would probably call it a diode or duode or something like that.

That's right!
A Diode has two terminals: Anode and Cathode
A Triode has three terminals: Anode (or Plate), Cathode and Grid.
