The 10F1 is an early all glass amplifier pentode. The high impedance suggests applications with tuned circuits as anode loads, such as RF, or more likely due to the high gain, IF amplification in superhet radio or radar receivers.
The pins are located equi-spaced around the base circle and the metal skirt and spigot aid location. The pins are short and hard as was the case with early all glass designs.
The thin glass tube envelope is 19 mm in diameter and, excluding the B8A base pins, is 51 mm tall.
