The 6N9P is a medium impedance double triode for voltage amplification and phase inversion in audio amplifiers. It has a gain of 70 and a wide glass envelope with pinch and hairpin heater wires.
Tube 6N9P or Röhre 6N9P ID40237, Double Triode, Octal (Int.Octal, IO) K8A, USA 1935 and Audio Frequency shown. Radio tubes are valves.
Sino 6N9P also 250V but not cheap as the Russian 6H9C. G. gabdx. Member. Joined 2008. amplificateurslegrand.ca/ 2016-05-08 7:17 pm #4 2016-05-08 7:17 pm #4 There is no difference at all with 6H9C and the best 6SL7GTB up to 400V. I never had any issue using the soviet equivalent.
I use 2 separated B+ rails for L and R channels (6n9p anode and El34 screen) each with it's own 10K resistor and 47uF Cap. Cathode bypass resistors of EL34's are lowered to 225 ohm (actually left channel tube is running at 22,5 W plate dissipation and right tube at 19,3W) and i ordered potentiometers to be mounted in place of resistors to bias ...
The 6N9P is a twin triode pre ampflier valve and is the same as a 6SL7. There are many makes of this valve and would depend how much you wish to spend. Evatco up in Queensland would be a good source for EH's, Sovtek, JJ's or others. Helps to pay a bit extra for matching and testing for low microphonics. Edited December 4, 2010 by NT3 info
