I got a couple of the subject tubes which are supposed to
be "glow
modulator tubes". Best I can determine is that the light
output will
vary with current but I can't find data sheet googling.
If anyone has
pinout and/or data I'd sure like to see it. I think it
might be a mid
1960s item as my 1957 Sylvania manual doesn't show it.
thanks

Everyone replies, and yet you get no answers,

R-1131C,D
Max dcv 150
ma. 3-25
peak ma. 55
starting voltage 225
crater dia. .093
candelpower .2@25 ma.
light color white

What is the pin arrangement?

This Sylvania industrial tube catalog has ratings only, and
sadly no pinouts. It does say the light beam can be modulated
up to 1 mhz. Pretty good bandwidth for old technology.
