FIVRE L63 6J5G MINT boxed £ 800 quartet.
Description
The L63 was first introduced in 1938 as a valve with octal base made by the MO-V.
The American counterpart was named 6J5G.
With 6.3 Volts heater it is basically half a 6SN7GT. Basically two L63 make one 6SN7GT!
The FIVRE L63 shown here are among the most sought-after valves.
Metal ring base with seal dated mid 50s, something to go for.
They come with original boxes as mint as they can be and have been tested with AVO VCM 163:
