eBay 6N1P / ECC88 / 6DJ 8Tested With Roetest V 10 NOVOSIBIRSK From 1967 6N1P / ECC88 / 6DJ8 Russian Tubes By VOSKHOD Factory (rocket) Tubes From 1967!! Improved stability and extended lifespan Tested With Roetest V10 NOS/NIB Tested with Roetest V10, «the Rolls Royce of tube testers» [emissionlab quote], a wonderful german professional system for testing tubes, it shows everything about a tube. The tubes passed all quality tests (vacuum, leaks, shorts etc.), measured with Roetest, the buyer will get all data, actual datasheet – test protocol, for each tube. Those who use tubes are more familiar with terms like bias, gain (µ), plate current, slope/transconductance, and maybe someone is wondering what the term „D of plate” in the measured data means. Its value in itself is not so important but it is useful to calculate the other parameters taking into account Barkhausen’s tubular formula S x D x Ri = 1 (slope * penetration * internal resistance=1), where D is –dUg/dUa at Ia=const. Barkhausen vas a german physicist, he was “the guru” of tubes, his theory and formulas guided the entire period of electronic tubes. . 6N1P equivalents/ replacement 6n1p is a direct replacement for the following tubes, and the only difference is the higher heating consumption, which is easy supported by quality amplifiers/preamplifiers. For an economical, inexpensive amplifier that is made with power supply balance close or beyond limits and that already works with power transformer hot, it can be a problem. In the same socket without any modification, you can listen with approximately the same amplification, 6N1P, 6N1P-EV, ECC88, E88CC, E188CC, 6DJ8, CV5358, M3624, CV2492, CV2493, PCC88 (this one normally needs a 7V heater voltage), 6922, CCa, 6N11, CV50064, 6N23P, 6N23P-EV. You can use 6n1p as a replacement for ECC81 or ECC82 but only after taking care of the heater differences, easy to adapt. I have personally tried, in the same socket of my test amplifier, 6N1P, 6N1P-EV, ECC88, E188CC, E88CC, 6N23P, 6N23p-EV, 6N2P, 6N2P-EV (much higher gain for the last 2, like ECC83 / 12AX7). I have even successfully tried E288CC and 6N6P (and ECC82, ECC81, E80CC with heater modifications). Recently I have decided to listen to any tube I sell. So I listened for a minute or so hundreds of each tubes I have mentioned above. I have noticed no sound differences, but I can’t say I have the sensitive ears of an audiophile. So I can guarantee that you can hear clear, undistorted music if you use the 6N1P as replacement and I guarantee the electrical parameters resulting from measurement and sorting tubes. For sound type, life time, noise, microphonic, and other specific features compared to the replaced tube, please check the catalogue sheets and read different opinions on the internet. It is also possible to get a different sound for a different amplifier. For example, E188CC is made for low noise/low signal applications, E88CC gold pin is a higher class quality than ECC88 etc. Do not use the tubes over the maximal values recommended in datasheets. If you do this, it will be on your risk! And safety first: turn off the device, wait a little and always use gloves when handling the tubes. The tube may be hot or it may break when inserted or extracted in/ from socket!
