Western Electric 91E

Western Electric 91E

Made for listeners who demand the absolute finest in tube sound.

Introducing Western Electric flagship integrated amplifier.

The Western Electric 91E is the latest advancement in single-ended sound, energised by its famous predecessor the WE 91A.

At double the power, you have never heard the 300B express itself like this before.

A new level of performance has been achieved with a completely new approach to SE amplifier design.

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

Double the Performance

Trouble-free, noise-free, and double the power of traditional 300B amps. Made possible by patented circuit design.

A New Classic

They are proud to continue a legacy of quality, American manufacturing

Ships with Tubes

The Western Electric 91E ships with new production 300B’s, the most popular vacuum tubes in the world.

• The Western Electric Type 91E is a Class A, single-ended (SE), integrated amplifier for high-fidelity audio reproduction.

• The 91E was made for the Western Electric 300B to provide end users the highest possible performance and quality.

• Steered Current Source Technology (SCS)
  Experience double the traditional output power with advanced, single-ended (SE) circuit design. This new level of performance is reached by using a fully linear, steered current source (US Patent 10256776) controlled exclusively by the tube’s output voltage. The excess of common large output transformers and associated hysteresis is eliminated, and as a result, lush detail in the midrange and masterfully articulated upper and lower frequencies are revealed.
• Stepped Logarithmic Attenuator
  A stepped logarithmic attenuator is used to mimic the response of human hearing. The attenuator consists of only discrete resistors in a ladder configuration that are switched in and out of circuit to produce a logarithmic attenuation of the output signal.
• Interchangeable Transformer Block
  The standard 8-ohm transformer block can be interchanged with the optional 4-ohm or 16-ohm version. This feature is unique to the 91E Integrated Amplifier and allows users to match speaker impedance for improved fidelity. Single impedance transformers maintain lower winding capacitance normally vitiated with multiple tap transformers.
• LCD Display
  A bright and easy to read color display shows the selected input, attenuator level, and VU meter. The display also shows settings which can be adjusted by the included remote control. The display is dimmable.
• Remote Control
  The included infrared remote control allows for quick adjustment of amplifier settings such as input levels, balance, and display dimming.
• Six Audio Inputs
  Up to six (6) source devices can be connected during amplifier operation.
• Auto-Bias
  Microprocessors automatically bias the 300B tube pair each time the amplifier is powered on. No manual adjustment is necessary.
• BT Compatibility
  BT compatible audio input is available for wireless convenience.
• Software & Firmware Updates via Ethernet Connection and USB
