The VT501 is a small low power VHF transmitting beam tetrode used in WWII, it is also known as the CV1501.
Our exhibit is from a post-war TRF (tuned radio frequency) broadcast radio receiver. These receivers were made in large quantities from kits in the late 1940s. In this simple receiver the VT501 was used as the audio output valve. This example predates the current tendency to use transmitting valves for audio use by 50 years.
The wide glass tube envelope is 28 mm in diameter and, excluding the IO base pins, is 85 mm tall.
