Power transformer design is a very specialised field, and our transformers are the result of many years of closely co-operative development with our manufacturers. The 250 has four regulated power supplies each of which is rated at 40 volts and able to deliver more than 15 amps. The highest quality components are used throughout, with great attention to detail construction. Our exceptionally fast and robust output transistors are made for us to our own specifications. Our standard protection circuitry is augmented by a power supply trip which operates if 18 amps is demanded for more than 10 micro-seconds. Heatsink temperature is monitored by a thermal cut-out which resets automatically.\u003cbr\u003e\nSpecifications:\u003cbr\u003e\nPower Output: 70 W per channel into 8Ω\u003cbr\u003e\nTransient: 400 VA\u003cbr\u003e\nVoltage Gain: +29 dB\u003cbr\u003e\nInput Impedance: 22 KΩ\u003cbr\u003e\nFrequency Response: -3 dB at 3 Hz \u0026amp; 40 kHz\u003cbr\u003e\nMains Supply: 100 V, 110 V, 120 V, 200 V, 220 V or 240 V, 50 or 60 Hz\u003cbr\u003e\nDimensions: 460 (W) x 300 (D) x 76 (H) mm\u003c\/p\u003e","brand":"2ndhandhifi","offers":[{"title":"Default Title","offer_id":50986791633237,"sku":"62643","price":849.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0958\/1094\/5365\/files\/IMG_2820-scaled.jpg?v=1753876205","url":"https:\/\/2ndhandhifi.co.uk\/products\/naim-nap-250-power-amplifier-2","provider":"2ndhandhifi.co.uk","version":"1.0","type":"link"}
