Description

Another variation of the NR73 is the ECC31 made by Mullard.

The ECC3 is a medium μ double triode with a common cathode. The valves you see here are basically ECC31 branded NR73.

The ECC31 has same current and mA/V of ECC32 but different pin’s layout

Valves you see here have full thick getter early type 1950s. Earlier logo.

All valves tested at 6mA 100% emission
