The amplifier with some marks of wear over the years.Have been professionally serviced, tested, cleaned, and replaced components only that were out of spec. Most parts are still original.You will need a step-down transformer to run it in the UK or Europe. This is not included in the purchase, but I can guide you in purchasing it or supply it for an extra fee. Also, It can be converted for 240V internally for about 150-170£ extra fee (depending on amp power) if you request it.--------------------------------------------------------------------------------------------The Yamaha A-S1000 utilizes Yamaha's latest amplification technology to deliver an exceptional acoustic performance.With the Yamaha A-S2000 and now the A-S1000, Yamaha has taken the bold step of using a floating balanced configuration to update the power amplifier for serious music fans. The use of four sets of floating power supply units (not connected to earth), provides further operating precision. The result is very low levels of noise and distortion for exceptionally pure and transparent sound quality.The AS1000 is equipped with height-adjustable, solid steel feet that maximize stability and thoroughly dampen any external vibration.FeaturesI/O (input to output) Direct Symmetrical DesignFloating balanced power ampThree parallel volume and tone controlsFour large capacity power supplies for power ampShunt-type local regulators for preamplifierDiscrete headphone amp for low-impedance driveSpecially designed feetSpecificationsMaximum Power: 160 W + 160 WHigh Dynamic Power/Channel: 105/135/190/220 WDamping Factor: 160Frequency Response: 5 Hz-100 kHz (+0 dB/-3 dB)RIAA Equalization Deviation: 20 Hz-20 kHz +/-0.5 dBTotal Harmonic Distortion (CD to Sp Out, 20 Hz-20 kHz): 0.015Signal-to-Noise Ratio (CD): 98 dB (S: 150 mV)Input Sensitivity (CD): 150mV/47k ohmsDimensions (W x H x D): 435 x 137 x 465 mmWeight: 22 kgDisclaimer:Although I take every precaution in managing my hi-fi and hi-end products, there is a possibility that small scratches may occur during display and storage.

Yamaha stands as one of the world's most storied audio manufacturers, with roots extending far beyond consumer electronics. Founded in 1887 by Torakusu Yamaha in Hamamatsu, Japan, the company began as a reed organ manufacturer before expanding into pianos and eventually becoming a comprehensive musical instrument maker. This deep heritage in acoustics and materials science would prove foundational to its later audio ventures. The company operated under its original name, Nippon Gakki Co., Ltd., until 1987, when it was renamed Yamaha Corporation in honor of its centennial.
Yamaha's entry into high-fidelity audio proved transformative for the industry itself. In 1954, the company released the Yamaha Hi-Fi Player, widely recognized as the world's first audio component to bear the "Hi-Fi" designation in its name. The company subsequently built a comprehensive product portfolio spanning amplifiers—beginning with the acclaimed A-100 in 1960—speakers, turntables, and digital audio equipment. The NS-1000 speakers, introduced in 1974 with beryllium drivers, became iconic reference monitors. Yamaha also pioneered digital audio technology, shipping the world's first CD recorder in 1988.
Today, Yamaha occupies a distinctive position as a mid-to-high-end generalist rather than a niche specialist. The brand commands respect among both casual listeners and serious audiophiles, balancing accessibility with genuine engineering credibility. Its reputation rests on six decades of consistent innovation, proven reliability, and the unique advantage of applying musical instrument expertise to audio reproduction. Vintage Yamaha components remain highly sought by collectors, while current products maintain the brand's tradition of delivering performance and durability across multiple price tiers.
