WE 300B
Western Electric™ 300B Vacuum Tube
Classification: Moderate power, filamentary triodes for Class A service.

Application: Audio-frequency amplifier in positions where power outputs of approximately ten watts or less are required at relatively low plate voltages.
The WE300B is a vacuum tube with a long history of high performance and great sound. The current generation of the 300B is receiving praise from a wide range of listeners and amplifier producers alike. Surf on in for more information!

WE300B tubes are available in Singles or as Matched Pairs, Quads or Octets. The performance curves for each tube produced are stored in the computer which controls the test sequence. Another computer then performs the matching algorithm, working from the entire single tube
inventory, to find the best matched pair for each order. Matched Pairs, Quads, and Octets are shipped in a laser engraved cherry box which protects the tubes in transit, as well as assuring authenticity.

Each tube ships with a card which contains the actual performance curves for that particular tube, not just the design curves. Note the serial number and date of the test. Each card is printed on a printer attached to the test station. The curves are measured for each tube!
