WESTERN ELECTRIC 91E INTEGRATED 300B VALVE AMPLIFIER
The Western Electric 91E Integrated Amplifier is now available to pre-order.
We brought you the news of the Western Electric 91E Integrated Amplifier featuring their “back in production” 300B valves, three years ago. Now, despite the pandemic, the amplifier is finally available to pre-order.
WESTERN ELECTRIC 91E INTEGRATED AMPLIFIER
The flagship single ended 300B valve amplifier will be available in three finishes, nickel, black and gold. The amp is also Bluetooth compatible. Initial units of the Western Electric 91E are currently entering the final stages of assembly and quality inspection.
STEERED CURRENT SOURCE TECHNOLOGY
The 91E uses Western Electric’s patented steered current source technology. The parallel feed topology contributes half of the AC current to the plate (anode) of the 300B by modulating quiescent current. As a result, half of the power dissipation occurs in the tube, allowing for a greater output power of 20 watts per channel.
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 the 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 version. Western Electric says that this feature is unique to the 91E Integrated Amplifier. Single impedance transformers maintain lower winding capacitance.
WESTERN ELECTRIC 91E INTEGRATED AMPLIFIER LCD DISPLAY
A bright and easy to read colour 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 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.
