Double triodes 6N2P-EV (6H2П-EB) are 6N2P tube modifications with extended lifetime (not less than 5000 operating hours under prescribed conditions) and improved reliability. These tubes are direct replacement for the 6CC41 from manufacturer Tesla and the chinese 6N2 tubes. Close by characteristics to the 12AX7, ECC83 or E83CC. 6N2P-EV tubes are a replacement for the 12AX7 in any typical amp application, but they have 6.3V heater voltage and would need a different wiring than stock 12AX7's, so it is not a direct replacement. Nowadays already scarce triple mica version. Tubes were selected from a higher amount of tested tubes (samples of the pairs are in the gallery). New old stock tubes. Manufacturer: Voskhod. Year of production: 1971. Will be delivered in modern white boxes with measured parameters attached.
