In 1936 Western Electric commissioned the 91A amplifier and manufactured, installed, and maintained these early sound systems. Thus introducing a burgeoning Hollywood movie industry and moviegoers worldwide to the magical, yet naturalistic wonder of high fidelity sound reproduction. The 91E continues the legacy of Western Electric sound.
The Western Electric Type 91E Integrated amplifier is a Class A, single-ended (SE) design for high fidelity audio reproduction. It has more than double the conventional output power of the Western Electric Type 300B tube. This innovation was made possible by patented SE circuit topology. The 91E is made for the Western Electric 300B, to provide listeners with the highest possible performance and quality.
Many years beyond the vacuum tube era, the 300B remains the triode of choice for serious music lovers worldwide. The 91E, with its patented steered current source technology (SCS), has the best possible design allowing the 300B to truly sing, elevating the listener’s audio experience along with unforgettable industrial design. The 91E is a showpiece that balances rugged retro features, like nickel-plated handles and an oversized attenuator knob, with stylish glass tube caging and an easy-to read LCD screen for an overall modern elegance.
