Released in 1979 as the successor to the SIT-powered B-3, it was engineered to match that prized SIT sound without using SITs, via Yamaha's new Linear Transfer Circuit: a triple push-pull output running custom copper-stem transistors to crush the crossover distortion that usually plagues big bipolar amps. The result is huge, effortless power at very low distortion, with that composed, unflustered Yamaha delivery. Understated black styling, vault-like build, and far more amplifier than its plain looks suggest.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eFEATURES \u0026amp; PROS:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e240 Watts Per Channel:\u003c\/strong\u003e Serious, effortless power into 8 ohms, ready for demanding speakers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLinear Transfer Circuit:\u003c\/strong\u003e Yamaha's triple push-pull design that tames crossover distortion for an almost SIT-like smoothness.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCustom Output Devices:\u003c\/strong\u003e Yamaha-developed copper-stem 2SC2707\/2SA1147 transistors for low distortion and wide bandwidth.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeir to the SIT Amps:\u003c\/strong\u003e The follow-up to the legendary B-3, built to surpass it.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNatural Sound Voicing:\u003c\/strong\u003e Composed, neutral and non-fatiguing, made for long listening.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTank Build:\u003c\/strong\u003e Heavy, quietly handsome late-70s Yamaha engineering.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eTHE WORD:\u003c\/strong\u003e Yamaha's own amplifier history records the B-5 as the heir to the SIT-powered B-3, developed to match that charming SIT sound through the new Linear Transfer Circuit while delivering 240 watts per channel at just 0.005% distortion. \u003ca href=\"https:\/\/usa.yamaha.com\/products\/contents\/audio_visual\/hifi_components\/hifi-history\/separate-amplifier\/index.html\" target=\"_blank\" rel=\"noopener\"\u003eRead more in Yamaha's amplifier history\u003c\/a\u003e.\u003c\/p\u003e\n\u003chr\u003e\n\u003cp\u003e\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eModel:\u003c\/strong\u003e Yamaha B-5\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eReleased:\u003c\/strong\u003e 1979 (produced to around 1982)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Natural Sound stereo power amplifier\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower:\u003c\/strong\u003e 240W per channel into 8 ohms (20Hz to 20kHz, 0.005% THD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutput stage:\u003c\/strong\u003e Linear Transfer Circuit, triple push-pull bipolar (copper-stem 2SC2707\/2SA1147)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDamping factor:\u003c\/strong\u003e 200; signal-to-noise: 123dB; response: 10Hz to 100kHz\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMains:\u003c\/strong\u003e many B-5 units are 100V Japanese-market; please confirm voltage (a step-down transformer may be required)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCondition:\u003c\/strong\u003e used, functional\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yamaha","offers":[{"title":"Default Title","offer_id":49726438703343,"sku":null,"price":12500.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0751\/5992\/9071\/files\/IMG_7755.jpg?v=1780999752","url":"https:\/\/innerpieces.art\/products\/yamaha-stereo-power-amplifier-clean-natural-sound-muscle-in-basic-black","provider":"Inner Pieces","version":"1.0","type":"link"}
