A pair of NOS 6Н23П / 6N23P Reflector
2 pcs. 1975. EXTRARARE HOLY GRAIL! To get the best sound!
TESTED 100+%. USSR. OTK.
The measurements were carried out on an IL-14 tube test bench. Results of measurements are on photo1.
Proper selection of tubes is very necessary to get the correct and high-fidelity mode of the
amplifier. During the
measurements tube is set to conditions
identical to the amplifier. The sameness at maximum modes is checked at higher
voltages/currents.
Pay some attention to the fact that these unique and remarkable 6n23p reflector tubes of 1975 are a vintage product. Therefore, it is very important for us to carry out a thorough and high-quality training of tubes in different passport modes before selling. Testing requires a lot of time and constant monitoring of the process. To provide measurements by highly stable voltage sources and multi-turn variable resistors which stabilize anode currents may take a lot of time per just a pair of tubes.
That's exactly why after such a training tubes become more reliable, they spread their characteristics wide. Be sure the result is worth it. We do it for you.
