Sensibly equivalent¶ to:
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.
