[Collins] RE: tube type 0A2

Sorry Yves (and others), here are the two messages that basically all
the others articulated in one way or another.

Dick,

Basically, the WA tubes are ruggedized versions of standard tubes.
Military
gear uses a lot of WA type tubes, for example.
Perhaps someone else on the list will add something to this.

The WA is supposedly a "ruggedized" version of the
normal OA2.  All of them will have slightly varying
regulated voltage.  The nominal value is 150 volts,
but it can be a little higher or a little lower,
depending on the tolerance of the individual tube.
They are interchangeable under all conditions.
