For your prime consideration is this vintage Western Electric 422A rectifier tube duet made in the USA. This pair is new old stock and includes the original boxes and packing material. The 422A is a double diode with indirectly heated cathodes. It is used as a full wave rectifier to supply direct current from an alternating current source. This pair is in NOS condition and both tubes test as strong as they get. If only the best will do, these are the pair for you.
Heater Voltage: 5 volts Maximum Peak Inverse Voltage: 1800 volts Maximum DC Output Current: 400 mA
