The KT101 is an audio output beam tetrode. With a load of 3,000 Ω and a cathode resistor of 180 Ω the KT101 would generate 3.8 W at 12% distortion. The KT101 is also specified for use strapped as a triode.The KT71 on an IO base is a similar valve.The reverse of the glass envelope carries the paper Marconi label that looks to be from the 1950s.The wide glass tube envelope is 32 mm in diameter, and excluding the B8Bbase pins is 69 mm tall.Reference: 1040. |
