Western Electric 91E Integrated Amplifier
A single-ended, integrated amplifier made for listeners who demand the absolute finest in tube sound
Introducing a revolutionary new integrated amplifier from Western Electric. Meet ambitious, single-ended sound inspired by its famous predecessor, the WE 91A.
Experience double the power. A never before realized level of performance has been achieved with a completely new approach to SE amplifier design. Developed over five years, the 91E’s circuitry intelligently steers the parallel feed constant current source (SCCS), allowing the tubes to deliver more than double their previously rated output of 7-8 watts. You’ve never heard the 300B like this before.
Comes fully tubed with JAN 12AT7 and Western Electric 300B. Choose from Black, Nickel and Champagne finishes.
Amplifier includes a Limited Warranty of ninety (90) days to the end user. The Limited Warranty period may be extended to three (3) years after the product is registered with Western Electric.
91E amplifiers are specially prepared for each owner. For this reason, we ask that you allow up to thirty (30) business days for inspection and quality checks to be completed. You will be notified via email if more time is required.
Initial units will ship in spring 2022. Customers outside the United States may be redirected to an authorized dealer in their region. In most cases, refunds are not allowed.
