The KT45 is rated as an audio output device with over 7 Watts output from a single stage. But the peak anode voltage is rated at 8,000 Volts. This clearly marks it out for duty as a line output stage in television type applications and indeed this was its intended use. The maximum anode dissipation is 21.5 Watts.The KT45 appears to be a re-issue of the pre-war KT44 and has identical ratings.The classic envelope is 53 mm in diameter and, excluding the B7 base pins, is 127 mm tall.References: 1043. Type KT45 was first introduced in 1947. See also 1947 adverts. |
