Description

Tubes set for NOUBSOUND 6P1 amp and for other home made amplifiers. 2 pcs x 6N8S (matched pair ) + 4 pcs x 6P1P (matched quad) + 1pcsx5C4S(kenotron) New OLD STOCK, NOS, Soviet military tubes Tubes 6P1P-EV NOS beam tetrode from russian production, military specs (-EV = longer life >5.000h and better mechanical stability), for preamps and poweramps und mini-Preamps (for example used in the Madamp G2 ). Life >5.000h for power-amps, can replace EL84, but different pinout!. 6P1P made by Svetlana (and of any years) is much better in quality and, most importantly, in reliability . Tubes made in 1970 -83year Manufacturer: Svetlana Compare to: EL90/6AQ5 => 6V6 Pinout: 1=A, 2=g2, 3=K, 4=H, 5=H, 6=A, 7=g1, 8=K, 9=g2 Typical operating values: Filament 6,3V/0,5A, Ua=250V, Ug1=-12,5V, Ug2=250V, Ia=45mA, Ig2=5,5mA, S=4,9mA/V, Ri=58KOhm Maximal operating values: Ua=250V, Ug2=250V, Pa=12W, Pg2=1,3W, Ik=70mA, Ukh=190V, Rg1=0,5MOhm Socket: Noval 5c4S - Two-anode kenotron, for rectifying alternating current of industrial frequency 50 Hz. Technical characteristics of 5C4S Filament voltage - 5 ± 0.5 V; Filament current - 2 ± 0.2 A; Nominal anode voltage (constant) - 50 V; Nominal anode current (for each diode) - no less than 300 mA; Anode current limit (average value) - 62 mA; Limit anode current (amplitude value) - 375 mA; The anode current at the moment of switching on is the maximum (amplitude value) - 1.25 A; Anode voltage reverse limit (amplitude value) - 1.35 kV; Rectified current (for each diode) - at least 122 mA; The voltage of the secondary winding of the transformer is 2x500 V; Filter capacity - 4 µF; The resistance in the anode circuit is 4.7 kOhm. The LOT off : 2 pcs x 6N8S (matched pair ) + 4 pcs x 6P1P (matched quad) + 1pcsx5C4S(5Ц4С)
