Sylvania R1131C octal tube ?
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 |

See: http://www.radiomuseum.org/tubes/tube_r1131c.html for a little information. Unfortunately they require a membership fee to download the datasheet illustrated. Evidently these tubes were orginally used for early facsimile machines (the sort used to send newspaper wire photos) but the search shows it was also used extensively in vision research. Perhaps someone knows of a better source for the datasheet. -- --- Richard Knoppow Los Angeles, CA, USA |

Sorry. |

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 |

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. -- --- Richard Knoppow Los Angeles, CA, USA |

All in PDF form but _very_ large files. Pretty good, but not my idea of big files. That starts with very full CD images and up. I do not bat an eye at downloading full multiple DVD distributions of Linux. I have dual layer rewriters and media as well. |

Muirhead (UK) was the mfgr. of the receiver/printer units. I simply don't recall who mfg the tubes, though. They were octal based, however. |

I don't have a data sheet on that one, but I have the phototube volume of the RCA HB-3 which has some other more or less similar crater tubes listed. The data sheet has a chart of light output vs. current and it's not very linear, but it tries to be. They were used in some early computer plotters and in a bunch of chart recorders as well. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
