Western Electric 300BWestern Electric 300BUpdate: Western Electric is planning to begin shipping new production 300B tubes by late May.
This is the 300B tube against which all other 300B's are compared. Stereophile magazine placed this tube at the top of the 300B category, and this new production version is much easier to obtain than a vintage pair of bottles. Every triode is individually numbered, with its own test results included as well. The packaging is also exquisite: a cherry box engraved with the Western Electric name contains both sealed tube boxes. Each sealed tube box has a serial number sticker and a velvet lining where they can "lie in state" while awaiting the call to take center stage in your amplifier.


Availability: Out of stock.
