Where does this Teonex CV 4004 valve come from I know it is over 10 years old & probably 20 years old it is unused (NOS) also it was bought in bulk for a UK gov./Nuclear industry application. Suggested by the supplier to be Chinese valve, however they sound very good, I did a test buy, result, I just bought a larger order as my pre & maiin amp both use them.

I knowTeonex was a UK based suplier not manufacturer who marked up valves mostly from Europe & Japan
