Historic TubeMuseum, Tuxedo Park, New YorkEstablished in 1928 as a premier research facility in Tuxedo Park, New York, that attracted such brilliant and most visionary minds of the twentieth century - Albert Einstein, Werner Heisenberg, James Franck, Niels Bohr and Enrico Fermi to name a few. The Tuxedo Park lab attracted these top-flight scientists who experimented with audio, sound, time measurement, and radar (first klystron tube). Welcome to the ...

Most bargin-priced 6N6P tubes we see suffer from Heater-to-Cathode Leaks, so you get what you pay for. We have weeded-out any tubes with high gas or H-to-K leaks.
There is no "real" substitute, not ECC99 and not E182CC! Close but not identical.
Unique in their electrical design they share no replacement tube in the US or European numbering system.Excellent as a driver for power tubes like 845, 300B, or 6C33C.
BAT gear users should immediately give 6N6P a try without any other circuit modifications. You will be surprised in the improvement in sound.
CHOOSE WISELY!IN A WAY THAT SHOWS EXPERIENCE, KNOWLEDGE, AND GOOD JUDGEMENT.Question? Which Version Should I Buy? 6N6P or 6N6P-IChoose Wisely with our 6N6P, and not the I-version.The 6N6P-I 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 6N6P) ARE made only for Audio, and have a 2000 hour life.
Read here:
....."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 it's 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 are not made for audio.)
