The BOTW AC Power Supply is designed to upgrade AC-powered audio equipment, including phono stages like the Benz Micro PP1, and to serve as a direct replacement for the basic AC\/AC power supplies typically supplied with turntables from brands like Rega and Thorens.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe design is based on the company’s successful BOTW P\u0026amp;P ECO MKII linear power supply models, incorporating all the necessary features to deliver a noticeable difference in performance.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eWhy do you need the BOTW Upgrade AC power supply?\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eA standard, stock-supplied AC\/AC power supply is typically little more than a low-cost \"EL-type transformer\" housed in a casing. In contrast, the BOTW upgrade AC power supply is engineered to deliver the most stable and low-noise AC current possible, ensuring superior performance compared to conventional AC power supplies.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eStability\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eA low-cost EL transformer not only has the lowest efficiency among available transformer types but also suffers from poor load regulation. Load regulation refers to the difference in AC output voltage between no-load and full-load conditions. For an EL transformer, this regulation is typically around 20% or worse, which leads to instability and significantly degrades the performance of audio equipment.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eThe BOTW upgrade AC power supply is designed to achieve the highest possible load regulation. To accomplish this, it utilizes a highly oversized, audio-grade toroidal transformer. The combination of the transformer’s robust design and ample power reserve ensures exceptionally tight load regulation, providing enhanced stability and optimal performance for audio devices.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003e\u003cimg src=\"https:\/\/cdn11.bigcommerce.com\/s-6naz0isypk\/images\/stencil\/original\/image-manager\/sbooster-botw-ac-power-supply-enhanced-content-.jpg?t=1741973647\" alt=\"Sbooster BOTW AC Power Supply internal components\" width=\"1200\" height=\"700\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eLow noise\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eWith an AC\/AC power supply, one would expect the output to deliver a perfect sinewave of 50 or 60Hz. Unfortunately, this is often not the case. Any pollution present on the mains grid will also appear on the output of the AC\/AC adapter. To prevent this mains pollution from affecting the audio device, the BOTW AC power supply begins purifying the AC mains power immediately. It features a built-in dual-stage mains filter, an upgraded gold-plated audio-purpose fuse, and an earth line choke, all of which work together to remove unwanted interference before it reaches the transformer.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eTurntables\u003c\/span\u003e\u003c\/h3\u003e\n\u003cp\u003e\u003cspan\u003eTo make the BOTW AC power supply perfectly suited for turntable applications, the company has added electrostatic and high-frequency magnetic shielding to the transformer. Additionally, an anti-oscillation circuit with Wima capacitors guarantees stable operation of the power supply, regardless of the type of AC-powered audio device. Finally, a custom-made 16AWG shielded output cable with gold-plated connector pins is used to ensure low-loss distribution of the purified AC power to the device.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003e\u003cspan\u003eFeatures of the MKII to improve the power flow, reduce mechanical stress and to lower the internal impedance \u0026amp; resistance:\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eAvailable in 16VAC and 24VAC output voltage, on request in 10VAC, 12VAC and 18VAC\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eOversized high efficient audio grade toroidal transformer\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eTransformer with Electrostatic and HF Magnetic shielding\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eVery tight load regulation for stable operation\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eLow noise AC output\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eIEC 14 power inlet suitable for High-end mains cables\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eHigh performance dual stage mains filter with Earth line choke\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eAC mains overvoltage protection circuit\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eShort-circuit protection\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eThermal overload protection circuit\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eHigh quality X2 safety rated polypropylene film capacitors in the mains filter\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eHigh quality Wima polypropylene film capacitors in the AC PCB\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eAC output cable with:\u003c\/span\u003e\u003c\/li\u003e\n\u003cul\u003e\n\u003cli aria-level=\"2\"\u003e\u003cspan\u003eadditional shielding\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"2\"\u003e\u003cspan\u003ebraided sleeve\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"2\"\u003e\u003cspan\u003egold plated machined brass connector pins\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eHigh quality double sided PCBs with 2oz. copper and gold plated finish\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eCustom-made AC-plugs in most common sizes for maximum flexibility \u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eDimmable LED light\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eCE approved\u003c\/span\u003e\u003c\/li\u003e\n\u003cli aria-level=\"1\"\u003e\u003cspan\u003eMade in the EU\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"The Music Room","offers":[{"title":"16V AC","offer_id":51268242964761,"sku":"3237newSBOO-0001","price":459.0,"currency_code":"USD","in_stock":true},{"title":"24V AC","offer_id":51268242997529,"sku":"3237newSBOO-0002","price":459.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/4225\/1545\/files\/Sbooster_BOTW_AC_Power_Supply_1.jpg?v=1768981383","url":"https:\/\/tmraudio.com\/products\/sbooster-botw-ac-power-supply","provider":"The Music Room","version":"1.0","type":"link"}
