By utilizing direct-heated triodes and meticulously crafted components, it delivers an authentic sound reproduction that captures the original performance.\u003c\/strong\u003e\u003cbr\u003e\u003chr\u003e\u003cbr\u003eThe Simply 845 leverages pure class A amplification for both preamplifier and power output stages, fundamentally influencing audio fidelity. This design involves single-ended topology, allowing for a more linear signal path and reducing crossover distortion. The output transformers, uniquely custom-wound by hand, utilize thin laminations of iron and silicon optimized for minimal magnetic losses, enhancing frequency response and lowering harmonic distortion. The integration of specifically chosen capacitors, constructed with polypropylene dielectrics, minimizes inductive effects and maintains the signal integrity. Furthermore, its printed circuit boards employ thick electrolytic copper traces, ensuring superior current handling and overall electrical performance.\u003cbr\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDirect-Heated Triodes:\u003c\/strong\u003e The use of 845 tubes enhances durability and sonic clarity, resulting in a rich, dynamic audio experience.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandcrafted Transformers:\u003c\/strong\u003e Custom-designed output transformers optimize magnetic field interaction, minimizing distortion and extending frequency range.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePure Class A Operation:\u003c\/strong\u003e Ensures linear amplification without crossover distortion, preserving audio fidelity across all stages of signal processing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Quality Capacitors:\u003c\/strong\u003e Anti-inductive capacitors with polypropylene dielectrics maintain signal integrity by reducing parasitic effects.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRobust PCB Design:\u003c\/strong\u003e Thick copper traces and fiberglass backing improve current flow and decrease electrical noise.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotorized Volume Control:\u003c\/strong\u003e The RK27 potentiometer offers precise sound adjustment, crucial for high-quality listening environments.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eType: Integrated Valve Amplifier\u003c\/li\u003e\n\u003cli\u003eValves: 2 x 845 Selected, 2 x ECC 82 \/ 12AU7 Selected\u003c\/li\u003e\n\u003cli\u003eClass: Class A\u003c\/li\u003e\n\u003cli\u003eOutput stage topology: Single-ended\u003c\/li\u003e\n\u003cli\u003eMaximum Power: 23W\u003c\/li\u003e\n\u003cli\u003eBandwidth: 20Hz-50kHz, +0dB -1dB @ 12W\u003c\/li\u003e\n\u003cli\u003eFeedback Level: 14 dB\u003c\/li\u003e\n\u003cli\u003eOutput impedance: 6 Ohm\u003c\/li\u003e\n\u003cli\u003eInput impedance: 47 Kohm \/ 100 pF\u003c\/li\u003e\n\u003cli\u003eInput: 4 line level\u003c\/li\u003e\n\u003cli\u003eOutputs: 1 Tape, 1 Subwoofer\u003c\/li\u003e\n\u003cli\u003ePower Consumption: 300VA\u003c\/li\u003e\n\u003cli\u003eSizes: 37 cm x 26 cm x 57 cm (L x H x D)\u003c\/li\u003e\n\u003cli\u003eWeight: 30.5 kg - 67 lbs\u003c\/li\u003e\n\u003cli\u003eMain Fuses: 5x20mm – 6.3 A at 100V-120V\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Unison Research","offers":[{"title":"Walnut","offer_id":43088230154353,"sku":"URSIMPLY845WAL","price":54999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0642\/0571\/7617\/files\/simply845anglenocage.jpg?v=1774188117","url":"https:\/\/shopodsy.com\/products\/unison-research-simply-845-noce","provider":"ODSY","version":"1.0","type":"link"}
