6N2P ECC83 12AX7 7025 5751 double triode USSR Soviet NEW SAME DATE
The 6N2P also has slightly lower gain than a 12AX7. The 5751 tube may be operated from 6.3 volts at 350 mA (the higher current draw is for increased reliability) for use in avionics. Interelectrode capacitance, pF: Input of each triode is 2.35.
