The ME1401 sub-miniature wire ended triode was designed to be soldered into the circuit as reliability was deemed to be of the same order as the rest of the components. The anode (pin 2) is marked with a red paint spot.
The ME family were all instrumentation amplifiers with very high imput impedances and classified as electrometer valves.
The thin glass tube envelope is 9 mm in diameter and, excluding the lead out wires is 41 mm tall.
