Hi, I was putzing around and thought I might do a project with some old tubes. Little did I know that the ones I paid under $1 a while back and put them in a bin could get scarce now. Prices today were from about $30 each to $85. They are Nuvistors from early Russian (yes I know we are not real happy with the now) military. The type is 6C52H-B. What I was curious about was the logo. Who made them? Anyone know?
The "N" letter in Cyrillic is what appears to our eyes as "Н." So, for example, the phrase novi russki (new Russian) is "новый русский." That phrase, by the way, is a very derogatory remark. It's what the Russians used to call what some people now call "oligarchs." It has always had a very negative connotation over there. Too bad they don't actually do something about it other than calling them derogatory names. Then again, what would any individual do over there to object? They probably fear for their lives, their safety and their "freedom." It's not just the Ukrainians that are hurt by Putin's psychopathy. They're just the country he happens to be taking aggression upon this year. Anyway - sorry for the digression - I just wanted you to know that the "N" letter looks like an "Н" to us, much like the "S" letter looks like a "С" as in Светлана (Svetlana).
Hi Wayne, thanks...any idea what company?
Sorry - I went on and on about Russian stuff - but the point I was trying to make was the Cyrillic transliteration of "Nuvistor" is "Нувистор" and there is a Russian-branded product of that name with the logo you showed. What looks like an "H" in that logo is actually the Russian letter "N." Н у в и с т о р N u v i s t o r Нувистор 6П37Н-В (Nuvistor 6P37N-V)
