russian 6H8N ( 6N8P ) = 6sn7
Hi!
How is the russian 6sn7, both in quality and sound? The reason for asking is that I'we got a chance of bying a NOS/NIB bach from the Novosibirsk plant. But don't have any references to / expierience with them... Best regards Tonni |

Hi Tonni,
How is the russian 6sn7, both in quality and sound? I am using several Reflektor plant 6H8C dated 04/1984 in my DIY projects and have nothing to object, except maybe that for certain applications system matching seems to be advisable. But on the other hand old, I would do so with old American stock, too. Tom -- MS-DOS is the worst text adventure game I have ever played: Poor vocabulary, weak parser and boring storyline. |

I used many Novosibirsk tubes: 6SN7, 6SL7, 5V4G etc. and I never was
disappointed. As Mr. Schlangen already pointed out, tubes show a wide variability in their characteristics, and it is not so easy to get a matched pair of triodes inside the same glass bulb: this happens more frequently with Russian tubes, therefore it is sometimes better to get a bunch of them and sort 'em out. By the way: in the Golden Age of tubes, I remember that when the TV guy called in at my father's house to fix our old B&W TV set, he just used to shove in there the first tube he found in his junk bag, without ever caring about brand, "matchedness" & so on, nevertheless the TV lit up and worked. Ex-CCCP tubes are as good as any other but some "special quality" ones, and usually the difference is in terms of durability and/or microphony, not linearity.

Best regards Tonni Tonni, Performance wise OK, had some where the pins weren't soldered correctly and were therefore intermittent; that was a drag til I figured out what the problem was and resoldered the pins.

I use them too and find them to be ok. A friend says that they are very
microphonic. The sound is good for me. |

Hi Tonni ,
Has no 6SN7 yet - but some CV1985's ( 6SL7 SQ ) to experiment with... Maybe this is an option ?? It's a good sounding amp . http://www.triodedick.com/stan_en_ol...ver%20copy.gif Article in Dutch at : http://www.triodedick.com/stanley_en_oliver_1.htm Ronald . |
