Sylvania R1131C octal tube ?
Thanks for all the help..
I also found this on an old schematic where they show a 1 meg resistor across the 3 & 7. pin 3 cathode pin 7 anode -- 73 Hank WD5JFR "Richard Knoppow" wrote in message ... "gudmundur" wrote in message ... In article , says... 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 -- 73 Hank WD5JFR 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? -- --- Richard Knoppow Los Angeles, CA, USA |
