With its single-ended Class-A operation, it delivers a genuine and warm sonic experience.\u003c\/strong\u003e\u003cbr\u003e\u003chr\u003e\u003cbr\u003eThe SE300B Mono Amplifier employs the iconic 300B triode in single-ended operation, allowing it to achieve a maximum output power of 10 watts. This low power output is compensated by its high efficiency and the use of specially designed power coupling through a pair of EL822\/CV2382 tubes operated in triode mode, which further enhances linearity and minimizes distortion. Its zero-feedback topology avoids negative feedback loops, thereby preserving the harmonic integrity of the audio signal. The carefully crafted C-core output transformer ensures optimal transfer of energy while minimizing phase distortion, contributing to its dynamic and richly textured sound. Notably, the low noise operation engineered into its design combines DC heating of the 300B triode and a custom mains transformer, ensuring minimal interference and high fidelity even at low volume levels.\u003cbr\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAll-Tube Mono Power Amplifier:\u003c\/strong\u003e Uses a classic 300B filamentary power triode in Class-A operation for natural harmonic reproduction.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSingle-Stage Driver:\u003c\/strong\u003e Employs two EL822\/CV2382 pentodes in triode mode, providing high idle current for improved dynamic range without distortion.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eZero-Feedback Design:\u003c\/strong\u003e Elimination of feedback loops preserves the pure signal path and enhances the acoustic authenticity.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eC-Core Output Transformer:\u003c\/strong\u003e Custom manufactured to minimize phase distortion, ensuring efficient energy transfer from the amplifier to the loudspeaker.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpeaker Load Matching:\u003c\/strong\u003e Features precise 4, 8, and 16 ohm loudspeaker matching for optimal performance tailored to your audio configuration.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLow Noise Operation:\u003c\/strong\u003e Design choices, including DC heating and balanced cathode adjustments, significantly reduce residual hum and idle noise.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustom Mains Transformer:\u003c\/strong\u003e Crafted in-house to ensure optimized operation for various voltages with minimal electromagnetic interference.\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003ePower Output: 10 Watts per channel\u003c\/li\u003e\n\u003cli\u003eOutput Impedance: 4, 8, or 16 Ohms\u003c\/li\u003e\n\u003cli\u003ePower Tubes: 1 x 300B triode\u003c\/li\u003e\n\u003cli\u003eDriver Tubes: 2 x EL822\/CV2382 in triode mode\u003c\/li\u003e\n\u003cli\u003eOperation Type: Single-Ended, Class-A\u003c\/li\u003e\n\u003cli\u003eTopology: Zero-Feedback\u003c\/li\u003e\n\u003cli\u003eTransformer Type: C-Core Output Transformer\u003c\/li\u003e\n\u003cli\u003eDimensions: Customizable for various mains voltages: 230Vac, 100Vac, 120Vac, 220Vac, 240Vac, 245Vac\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"THÖRESS","offers":[{"title":"Default Title","offer_id":43088229335153,"sku":"THORSE300BPAPAIR","price":9000.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0642\/0571\/7617\/files\/thoeress-se300b-9_ebbc933e-1c84-4881-8828-942d91111dba.jpg?v=1774188079","url":"https:\/\/shopodsy.com\/products\/thoress-se-300b-mono-power-amplifier-pair","provider":"ODSY","version":"1.0","type":"link"}
