Lot of 4 pcs 6N23P Reflector tubes
Double triode
For buyers' information: Measuring 6N23P tube parameters such as mutual conductance and service life on import devices designed for ECC88 and E88CC tubes is incorrect.These devices are designed for the ECC88 tube, which is superior to 6N23P in many respects, and these indicators will be low even for new 6N23P .By purchasing a 6N23P tube, you agree that this tube is a replacement for the ECC88 in terms of plate current and transconductance, but other parameters (mutual conductivity, service life, etc.) for 6N23P are lower than those for the ECC88, and claims regarding these parameters are not accepted.
