Psvane Elektronisches Vakuumröhrenventil

Notice: the price is just for one tube,if you want to matched pair, please buy two tubes Some precautions about using high voltage power tubes:  Unlike other vacuum tubes such as KT88 or EL34, which typically run at 450V plate voltage, high voltage power tubes such as 845, 805 and 211 run at plate voltage 900V or even higher depending on your amp design. Due to the high voltage in the circuit, biasing an 845 / 805 or 211 amp improperly may expose you to lethal high voltage causing instant...

The beam power quadrupole KT88 has an anode ultimate power dissipation of 42W. In the audio amplifier, two tubes can achieve 100W power for the AB1 push-pull output, and KT88 can also be used in the electronic voltage regulator circuit. KT88 is similar to CV5220 and 6550 and can be used interchangeably.
