Unique in their electrical design they share no replacement tube in the US or European numbering system. CHOOSE WISELY!

Question? Which Version Should I Buy? 6N1P-EV (6Н1П-ЕВ)or 6N1P Choose Wisely with our 6N1P-EV (6Н1П-ЕВ) and not the OC-version. The 6N1P-EV-OC is a Bad choice because they are NOT made for audio and only have a 500 hour life. The ones you get from us, (plain 6N1P-EV) ARE made only for Audio, and have a 2000 hour life. Read here: ....."THE I" version is for pulse operation - and also it is 500 hours variation of the tube.... the one without the "I" is the one that can be used 2000 hours .... it seems that "I" one is no good for me.... to bad.... i will play with it when i catch the time - to see if those two will be good in line... and in future i will try to find only plain 6N6P versions ....The I variant is for impulse operation so its curves indicate positive grid voltages. Because of this it is also not tested for microphonics and noise as these parameters are of no importance for audio .... ( they are made as a pulse tube, and not tested at the factory for noise, because they ( I VERSION) are not made for audio.) CERTIFIED LOW-NOISE MUSEUM SPECIMENS TubeMuseum tested tubes takes the guesswork out of the process of selection delivering you the best Audio tubes that there possibly can be.
