The classic 807 beam tetrode: this exhibit was made in Canada by RVC.
The parameters given are for single ended use. When used in a class AB1 as a push pull pair with 600 Volts on the anode an output power of 65 Watts was normal.
The base cap carries the Marconi name as well as the RVC logo. The insulators are ceramic and the anode is blackened for efficient heat radiation.
The elliptical lower screen is an 807 characteristic.
The classic envelope is 51 mm in diameter, and excluding the UX5 base pins is 129 mm tall.
References: Data-sheet & 1040. Type 807 was first introduced in 1938.
