There is no bigger name in the history of vacuum tubes than Western Electric. Western Electric engineered, designed, produced or experimented with over 785 different tubes from 1913 - 1988. Many of these tubes were superb sounding audio tubes that are still in very high demand today. These tubes include the 101D, 205D/E, 211D/E, 274A/B, 300A/B, 310A, 348A, 350B, 396A, 417A, 421A and 437A, just to name a few. Tube World stocks one of the most extensive inventories of WE tubes on the planet. Stock changes daily and prices continue to increase due to the scarcity of most WE tubes. Look for special selected cryogenically treated Western Electric tubes called .

SONIC COMMENTS: -------------- Dear Brendan: Today, my friends and I compared WE 274B with different date codes; (engraved base, 1952, 1958, 1962) No surprise, the engraved base sounds the best. The 1950's sounds similar, but is inferior to engraved base. 1962 is much worse. But comparing to WE422, the 274B is better. We also compared the internal structure of 1952 with engraved base and 1958, we can see some portion of 1952 is similar to engraved base and some look likes 1958, it also means it did been manufactured in 1952. Thanks for your great tubes and hope to do biz with you again. Best Regards, Vincent Chen
