Add to Cart:

The beam power quadrupole 6L6G series, with its anode limit dissipation power of 19W, is used for Class A1, AB1 and AB2 amplification in audio amplifier. At the same time, these tubes can also be used in electronic voltage stabilizing circuits. These tubes are similar to 5881 and 6L6GC and can be used interchangeably.
