The KT88 beam power quadrupole tube has an anode maximum dissipation power of 42W. In an audio amplifier, when two electronic tubes are used for AB1 push-pull output, a power of 100W can be obtained. At the same time, KT88 can also be used in electronic voltage stabilization circuits.
KT88 is similar to CV5220.6550 and can be used interchangeably.
