6N1P Triode. Anyone Familiar?

[bob p]

I recently listened to some pricey Audio Research amps at a HiFi store. Much to my surprise, they used a Russian 6N1P triode for their preamp sections, and the EH6550C for their output sections.

I was a bit surprised by the EH 6550C, as I thought the Russians would be more likely to build KT88 than 6550. Whether or not the EH6550C is a real 6550 is another story, i guess.

My real question is whether anyone is familiar with the 6N1P. I've never heard of it, and I'm a bit surprised that a company like AR would build their entire line around what seems to be an odd Russian tube. Am I missing something?

The 6N1P is similar to the 6922/6DJ8, but ruggdised.

I know a few hi-fi designers using the 6N1P in place of a 12AX7 in high gain applications - phono preamps.

This tube is also used as an output tube in the Bumbox mini-amps that put out about 1 watt.

thanks everyone for the links. as it turns out i was only finding tube data sheets written in the cyrillic alphabet, which made it difficult to figure out what was going on. Rob, thanks for that link. i didn't have it.

i guess i might as well have looked it up in the Wikipedia: link (http://en.wikipedia.org/wiki/6N1P)

Hi Bob,
You might look at this (Latin characters):

If the above isn't enough relevant for your needs,just let me know and I'll scan for you some other tube catalogue pages (altough,books unavailable in US).
HTH!

The kit (Gilmore Jr) I recently built uses the 6N1P for power. I did a fair amount of research to find out about the tube since I'd never heard of it. My understanding is the 6N1P is not so mainstream, but well respected as a highly linear preamp tube and line driver among the HiFiers. Svetlana makes (or markets) a current production, and you can find info there: http://www.svetlana-tubes.com/#

I've been wondering what an all-6N1P amp would sound like??:p
