Why Orange 0A2 VR Tube?

[Ed Tanton]

I don't believe orange "0A2"s are 0A2's Greg. I forget the number, but
Tektronix used a VR tube in some of their 'scopes that was orange.
Different gas, different voltage. Somebody probably stuck one of these in a
receiver you saw... and a regulated voltage being a regulated voltage, it
probably worked. I don't remember the number, and if you find out the
parameters of it I'd appreciate it, since I have a VR-tube table within my
website <http://www.n4xy.com/VR_Tubes.html> . It may be that it's one of
the ones I already have found and listed-or it may be one I need to add.

Of course, if anybody else knows of one I don't have listed-or have
wrong-I'd appreciate knowing about it.
