If a lamp is low or not on at all, the tube is immediately rejected.From here, the tube is fully analyzed by proprietary testing equipment.The getter ring is excited and releases its material onto the inside of the envelope to form the silver getter. The last step, before the electrical tests, is the final visual inspection.A long-time Western Electric employee performs this inspection.Walk into an Urban Outfitters, coffee shop, or cafe in any arts district and you will catch wind of an audio craze that has blown through the younger generation – analog sound.Boycotting digital sound, those who seek warm, analog signals wish to receive their music in a more natural way – not unlike preferring a handwritten letter in place of an email.

The amount of care and attention to detail found at this plant is absolutely amazing.These tubes are actually built better than the older 300Bs.To my surprise, some of the manufacturing processes are greatly improved, making for a more consistent product.In the case where very low conductive water is needed for cleaning, de-ionized water is used.Click here to see a picture of the polishing pumps under the Kansas City Works.
