I got a couple of the subject tubes which are supposed

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

There is a Sylvania tube manual on-line at:
http://www.pmillett.com/sylvania_tub...als_online.htm

However, it does not cover the R1131C

Lots of other good stuff on this site including several
RCA tube manuals and many books. All in PDF form but _very_
large files.
