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

I have a Sylania Technical Manual of tube data sheets dated 1959 and have the blue add-ons to 1960, and that tube is not
listed anywhere in it.
Sorry.

Hi Robert,

I have some PDF's of scanned tube manuals(Eimac, Taylor RCA), I would love to trade a few for a pdf of the Sylvania Manuals.
If interested email me.

Cheers
