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.

SONIC COMMENTS: "Hi Brendan, Got the 350B tubes in; luckly I was able to match up a good quad using these, and some of mine. I'm using 3 W.E. 350B and one N.U., for my "Quad Classic monoblocks". Wow, what a great tube in this amp! This is fantastic! I've heard a lot of great tubes and amps, but this is special. It's music, 3d; just breathtaking good sound! I hope you get some more of these; if you do let me know and I'll be the first in line...thanks Brendan. Just wanted you to know that this was the best tube order I've placed yet; thanks a lot!

396A WE Kuhl-Tube Dual Triode (special-selected cryogenically frozen 396A WE) (These are the best sounding 396A available; very quiet, detailed, smooth 396A) SONIC COMMENTS: -------------- The 396A WE cryo treated pair arrived safe and sound some time ago. The 396A WE Cyro is a huge improvement over the stock 'chinese?' 5670. The background noise is non-existent, and I have an all tube setup: AI M3A and a 7 watt S/E 300B power amp, and dynamics are improved by an order of magnitude! The 396A tubes arrived safely to me (Sweden) yesterday. Directly I changed the (non cryo) WE 396A to your WE 396A. Having Mullard EL34 in the amps I started to listen and WOW! how is this possible? The music just came to me!! (Cowboy Junkies-Live double CD) NOW in perfect 3D, hearing the female voice floating in the room and ALL the subliminal nuances from the instruments in full glory AND later in the night changing the Mullards to Svetlana Cryo-Valve transformed the 3D to an almost perfect HOLOGRAPHIC EFFECT! This with Brimars 6SL7 and 6SN7 driver tubes. Tonight I try B65 and ECC33 Mullard for the 6SN7 part as I have found the Brimar 6SL7 outstanding as a tube in my amps, but ECC33 are still better, with B65 a little more "smeared". In short: The difference from China "396a" to WE was great , BUT changing to WE 396A cryo pair was a "shock" (positive) and as I see it you could charge 1000$ a pair for these tubes if you only see the performance. I surely would recommend all serious tube-lovers to try your cryo-tubes and for my part I dont understand the "fuzz" about "high-price" as Brendan takes the extra work and pin-points out the very best tubes in the business saving us some negative (and there are many) beings of inferior tubes.
