Matched pair 6J1P-EV (6Ж1П-EB) from manufacturer Nevz (Novosibirsk). Fully tested with the analogue L3-3 (Л3-3) precise tube tester, this tester is absolutely the best choice for matching these tubes, because it has the required cathode resistor in the testing circuit. These are pretty rare and exceptionally beautiful sounding tubes from the EF95 family, which are not usually available in larger quantities. The construction looks similar to the 6J1P Voskhod tubes from the 60s. The sound is impressive and very detailed. If you own Little Dot, Little Bear, Douk or any other chinese amplifier using these tubes, it is time to replace them with the vintage soviet quality. They have used high quality material back than and these tubes also do have the "gold-platinum" grid (what is in this case also mentioned in the original datasheet). The pairs will come really nicely matched, within 3% tolerance. And finally they are also audio tested directly in the Little Dot MK2 amp, so they are prepared for immediate usage in your device. Service life is not less than 5000 operating hours. Please look at the gallery pictures for more details.
