NOS 1974 MATCHED QUADForty-Eight (48) Year Old NOS NOS from 100 BULK RUSSIAN MILITARY MASTER CASE. NO INDIVIDUAL PAPER BOXES. NOS NEW, MILITARY EQUIPMENT 6N6PThese tubes were manufactured by the NEVZ, Novosibirsk, Russia Military Factory.These specimens are the “Best of the Best” selected for matched mA & GM within the QUAD.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 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. …”I am starting to wrap up my own power tube testing on my Little Dot LD MkII. It took me some time since the tube was so clear sounding with the gold grid 6N6P tube. …”The gold grid 6N6P power tube is punchier and more dynamic sounding than my standard Russian 6N6P tube. Both have good tonal range. The standard OTK 5 Russian 6N6P tube is a more relaxed and just a bit softer sounding tube than the gold grid Russian 6N6P. Both tubes are good, but the gold grid 6N6P tubes are hard to find. Both power tubes have great synergy with the EF91 CV4014 driver tube.On the other hand, the Sovtek 6H30 power tube is awful sounding. It was very thin sounding and had very little bass compared to the previous two tubes that I mentioned above. The EF91 GEC tube, which is just a bit brighter from neutral, just makes matters worse with the Sovtek 6H30. The synergy was not there.”… 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.)
