6P1P-EV = 6AQ5 = EL-90 Tetrode tubes. MATCHED PAIR! The 6P1P-EV (Russian: 6П1П-EB) is a Soviet-made miniature 9-pin beam tetrode vacuum tube with ratings similar to the 6AQ5, EL90 and the 6V6. Because of a different pinout (a 9-pin base versus 7-pin base) than an 6AQ5/EL90, it cannot be used as a plug-in replacement for these types, however, it will work in the same circuit with component values unchanged. Its maximum plate/screen voltage and dissipation ratings are actually slightly higher than a 6AQ5. Long-life! The tubes are NOS (never used),  manufactured on Svetlana factory, OTK-marked.   Tubes tested on L3-3 tube tester with parameters:   Un = 6.3V, Uc1 = 12.5V, Uc2 = 250V, Ua = 250V, Ukn = 25OV                                                                                         Number Date Ia S 20/K Dec-82 39.0 4.1 34/K Dec-82 39.0 4.0 where 100% is: Ia = 44mA, S = 4.9 mA/V   Name 6P1P-EV Type Output beam tetrode,long-life Application LF power amplification Cathode type oxide,indirect heating Envelope glass,miniature Mass,g 20 Filament voltage,V 6,3 Filament current,A 0,45-0,53 Anode voltage,V 250 Anode current,A 0,033-0,055 Anode power,W 12 Grid1 voltage,V minus 12,5 Grid2 voltage,V 250 Steepness,mA/V 3,8-6,0 Reverse grid current,uA 0,5 Microphnic noise,mV 200 Socket type rsh8 Payment  Please note that we accept PayPal-payments only!
