[sdiy] Difference in 2SK30, 30A, 30AY, 30 ATM, etc

[David Ingebretsen]

Hi list!

I'm trying to understand if there is a difference between the 2SK30, 30A,
30AY, 30T, 30ATM, etc. When I built my x0xb0x, it said to use the 30AY in
one location (if memory serves) if it was available. In my Red Square
project, some of the 2SK30s are marked 30, some 30ATM.

I can't find a data sheet which defines any differences, and actually can
only find a datasheet proper for the 30ATM. I have some 30s and some 30As.
Do I care which one I use?

I've seen that an NTE458 will replaces any of them, so as usual, I'm
confused.
