La description

KT*8 KT*4 KT**0 Series Beam power tube KT*8's anticathode limit dissipation power is *2W. In audio frequency amplifier, if two tubes are used to drive AB1, the output power can reach **0W. At the same time, KT*8 can also be used in electron firm press electrical route. KT*8 is the same with CV***0、***0, and can be exchanged each other.
