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. The maximum anode dissipation is 21.5 Watts.

The classic envelope is 53 mm in diameter and, excluding the B7 base pins, is 127 mm tall.
