Unknown tube logo
I have just bought some 6N3P tubes. I don't recognise the logo on them - the logo is this one:
 Does anybody recognise it? The tubes were made in '89, are marked with cyrillic text and come with a Russian datasheet. The logo is not on this list of Russian logos, so perhaps they are not Russian? Best regards, Mikkel C. Simonsen |

Perhaps the tubes are from the Ryazan plant. Smudge that logo, as shown in the chart, and what you provided is possible.

I just bought some 6n3p's as well. Not sure what I'm going to do with them. Just got some to try them out.
May I ask what you are going to use them for? |

Gintaras is a good man.
But I'd have to say I'm with Eli on this one. There is a striking resemblance between the logo you've shown and that of the Ryazan plant. They probably changed their logo a little bit for some reason. |

It doesn't look like the Ryazan logo to me at all - it looks more like the Shuguang logo to me. But did Shuguang make tubes (with Russian datasheets) for the USSR market?

I've mailed Gintaras to ask if he knows what factory they were made in.
