- ONE PAIR (2 pcs) - 6N6P (cyrillic 6H6П) Platinum Grade vacuum tubes. The 6N6P is a vintage 9-pin vacuum tube manufactured by NEVZ (Novosibirsk, Soviet Union). 6N6P tubes are regarded as exceptional audio tubes. There are two versions of the vintage 6N6P tube. This version is the "export" version of the tube, which is often marked "CCCP" on the glass envelope.
- UPGRADE FOR 6N6 TUBES – 6N6P (6H6П) vacuum tubes are an excellent replacement for the Chinese 6N6 tube used in Little Dot headphone amplifiers and in other audio amplifier circuits designed for use with the 6N6 or 6N6P tubes. IMPORTANT: 6N6P tubes should only be used as a replacement for Chinese 6N6 and Russian 6N6P tubes. Unless specifically approved by the manufacturer of your audio device, this tube is not a suitable substitute for any other type of 9-pin tubes.
- TESTED AND MATCHED by experienced engineers using Amplitrex tube testers to evaluate the electrical parameters of the tubes. Tubes are evaluated for plate current (ip), mutual conductance, tube gain, H-K leakage, gas and noise. Data labels with measured ip and tube gain are attached to the tube boxes. After matching, the tubes are evaluated for sound quality in an amplifier. If any deficiencies are found the tubes are not sold. Less than 50% of the 6N6P tubes we test and audition pass our standard for high fidelity audio use.
- TEST RESULTS CLEARLY MARKED on the tube boxes with data labels for ip (plate current and tube gain (µ) are attached to the individual tube boxes. Tubes chosen for these special matched pairs have good balance between tube sections and close electrical parameter matching between the tube sections and between individual tubes used in a matched pair (ip is matched within 8% and tube gain within 5%). Individual matched pairs will have identical date codes (date codes for the tubes we offer range from 1970 to 1991).
- BUY WITH CONFIDENCE - A decade ago we accumulated a large number of NOS 6N6P tubes and are now selecting the best of these tubes for our Platinum Grade matched pairs. We guarantee that the tubes selected for our matched pairs test at NOS levels. Tubes are supplied in our custom tube boxes (Riverstone Audio’s “Tube Cradle” boxes). Vacuum tubes sold by Riverstone Audio will have the "Riverstone Audio" name, logo and QC label on the boxes.
- Our Platinum Grade 6N6P (6H6П) vacuum tubes are backed by RIverstone Audio's 3-year warranty - THE BEST WARRANTY AVAILABLE in the audio tube business.
- 6N6P tubes can only be used in specific audio circuits designed for this tube; there is no similarity between 6N6P tubes and 6N6C, 6P1P, 6P6P or 6V6 tubes.
