The 91E doubles the power to 15 W, and achieves a new level of performance with intelligent circuits that steer the parallel feed constant current source, allowing this high power with extreme linearity and low distortion. The beautifully machined aluminum chassis is available in three finishes: Black, Nickel, and Champagne.\u003c\/p\u003e\n\u003ch4\u003eAbout Western Electric\u003c\/h4\u003e\n\u003cp\u003eFounded in 1869, Western Electric's history is intertwined with the history of transmitted and recorded sound. An American brand through and through, it was owned by AT\u0026amp;T until it was bought and revived in 1996 by entrepreneur Charles G. Whitener of Westrex Corporation. The goal was to manufacture vacuum tubes and high-fidelity audio equipment.\u003c\/p\u003e\n\u003cp\u003eIn 1997, a newly created run of Western Electric 300B tubes began shipping worldwide, to great excitement among the tube audio community. In 2017, a modern tube manufacturing operation was set up in Rossville, Georgia with the goal of modernizing 300B manufacturing, adding additional tube lines, and in-house research and design of new products under this proud revival of an original American brand.\u003c\/p\u003e\n\u003ch4\u003eSteered Current Source Technology (SCS)\u003c\/h4\u003e\n\u003cp\u003eWestern Electric’s patented steered current source technology uses a parallel feed topology that contributes half of AC current to the 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.\u003c\/p\u003e\n\u003cp\u003eThe 91E also offers autobias, so there's no need to worry about setting bias for your tubes. \u003c\/p\u003e\n\u003ch4\u003eStepped Logarithmic Attenuator\u003c\/h4\u003e\n\u003cp\u003eHigh-quality resistors are used in a ladder configuration to produce a logarithmic attenuation of the output signal, in a manner that imitates the response of human hearing.\u003c\/p\u003e\n\u003ch4\u003eInterchangeable Transformer Block\u003c\/h4\u003e\n\u003cp\u003eInstead of using multiple taps on the transformer, the 91E uses a single impedance transformer with optional output blocks. This offers higher fidelity due to the the lower winding capacitance of single impedance transformers. The 4 ohm block is sold separately.\u003c\/p\u003e\n\u003ch4\u003eOther Features\u003c\/h4\u003e\n\u003cp\u003eA tube amp for the modern day! The easy-to-read (dimmable) LCD display shows which of the six inputs has been selected, volume level, and also has a VU meter. The included infrared remote control allows for quick adjustment of amplifier settings such as input levels, balance, and display dimming. The 91E has two phono inputs and four stereo RCA line inputs. A Bluetooth audio input is available for wireless convenience. It has a line output and a preamplifier output.\u003cbr\u003e\u003cbr\u003eSoftware and firmware updates are delivered via an Ethernet connection and USB port.\u003c\/p\u003e\n\u003ch3\u003eIn the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e91E integrated amplifier\u003c\/li\u003e\n\u003cli\u003eRemote control\u003c\/li\u003e\n\u003cli\u003ePin-straightener (9-pin)\u003c\/li\u003e\n\u003cli\u003e2 x 300B vacuum tubes\u003c\/li\u003e\n\u003cli\u003e2x ECC81 vacuum tubes (Pre-amplifier, pre-installed)\u003c\/li\u003e\n\u003cli\u003e8 Ω output transformer block (pre-installed)\u003c\/li\u003e\n\u003cli\u003ePower cord\u003c\/li\u003e\n\u003cli\u003eSpanner tool (for removal and\/or replacement of 300B’s)\u003c\/li\u003e\n\u003cli\u003eBT antenna\u003c\/li\u003e\n\u003cli\u003eUser manual\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eOutput Power Per Channel\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003eAt 4 Ω and 8 Ω (THD 10%, 5%, 3%):\u003c\/strong\u003e 20 W, 16 W, 14 W\u003cbr\u003e\u003cstrong data-mce-fragment=\"1\"\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eTube Complement:\u003c\/strong\u003e 2 x Western Electric 300B, 2 x ECC81\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInputs:\u003c\/strong\u003e 2 x stereo RCA phono, 4 x stereo RCA line, 1 x Bluetooth\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eOutputs:\u003c\/strong\u003e 1 x stereo RCA line, 1 x stereo RCA pre, 1 x stereo speaker \u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePhono \u003cbr\u003eMC Sensitivity (10W \/ 4Ω):\u003c\/strong\u003e 70 μV\u003cbr\u003e\u003cstrong\u003eMM Input Impedance:\u003c\/strong\u003e 47 kOhms\u003cbr\u003e\u003cstrong\u003eMM Capacitance:\u003c\/strong\u003e 100 pF\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePower Consumption (Operation, Standby):\u003c\/strong\u003e 160 W, 0.3 W\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMains Fuse:\u003c\/strong\u003e 2 A slow-blow\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eBluetooth:\u003c\/strong\u003e  Standard v4.2, up to 96 kHz \/ 16-bit\u003cbr\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e 18.9\" x 15\" x 11.1” (48 x 38 x 28 cm)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 49 lb (22.2 kg)\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"Western Electric","offers":[{"title":"Nickel","offer_id":48541581279416,"sku":"WE-91E-NB-311","price":7999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1564\/1247\/products\/CopyofNickelFront-91E.jpg?v=1741630537","url":"https:\/\/upscaleaudio.pro\/products\/western-electric-91e-tube-integrated-amplifier-blem-2","provider":"Upscale Audio","version":"1.0","type":"link"}
