This exhibit is very much new old stock as the box has never been opened or the valve tested. The box is 50 mm square and 141 mm long and RVC had input from Marconi and General Electric and this is reflected in the brand names on the box.
The Type 32 was designed as an RF amplifier in battery operated receivers.
The top end of the box. Each side of the insert and sleeve are stapled together.
The base is also stapled in the centre of the four sides. If the corners are broken open the valve pins are available for insertion into a valve tester without removing the valve from the packaging.
The actual valve with the outer cylindrical screen being the most prominent feature. Note also the fluted top cap.
The RVC logo.
The pinch and lower screen. The latter connects to the screen grid and the grid wires can just be seen in the image.
The screen grid is close wound and obscures the inner grid. The anode can be seen as a solid cylinder just inside the perforated outer screen.
The classic envelope is 44 mm in diameter and, excluding the UX4 base pins, is 109 mm tall.
