SV83 Audio Power Pentode

Chinese made equivalent of Svetlana SV83 / Russian Audio Power Pentode

General Information

The Chinese equivalent of SV83/6?15? (6P15P) is a 12 watt power pentode suitable for audio use as a driver or output device in amplifiers. Similar to the EL84 but with SV83/6?15? (6P15P) pinout. If using in circuit as a replacement to an EL84, adjustments to the basing connections must be made.
