The 6N1P ((ロシア語:6Н1П)) is a Russian-made miniature 9-pin medium gain double triode vacuum tube intended for use as a line audio amplifier and cathode driver. Basic data: * Uf = 6.3 V, If = 600 mA * µ = 35 * Ia = 7.5 mA * S = 4.35 mA/V * Pa = 2.2 W The 6N1P has similar ratings to the 6DJ8 and in the past was sometimes rebranded as such, however differences between the two types (the 6N1P requires double the filament current and has only one third the S value) mean they are not directly interchangeable. The S is about 4.35 ma/V, the 6DJ8/ECC88 has a S of 12.5 ma/V and a gain of 33 and a lower internal resistance. The curves of the 6DJ8 have a better linearity too. It is therefore inaccurate to say that these two tubes are identical. The closest western equivalent to the 6N1P is the well known 6BQ7A. A ruggedized/extended ratings version of the tube is designated 6N1P-EV ((ロシア語:6Н1П-ЕВ)). It has currently found a use as a driver tube in hi-fi tube amplifiers (such as Audio Research models VS55 and VS110) because of its excellent low distortion and low noise characteristics. The tube is manufactured by the "Voskhod" plant in Kaluga, Russia (see ()) and is distributed in the West under the Sovtek and Svetlana brand names. == See also == *6DJ8 *6N2P *6N3P 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「6N1P」の詳細全文を読む スポンサード リンク
