I have a beautiful Yamaha CA-810 amplifier that has a such a beautiful sound coming from it. This unit was in production from 1977-1979, the power output on this amp is 65 Watts Per Channel. The unit weighs in at 26lbs with a massive transformer inside. I am asking for 900 OBO, I have tested the unit and it plays as it should the unit is sold as is being of its age. Here is a bit more about this unit during its production. The Yamaha CA-810 is a vintage integrated amplifier produced between 1977 and 1979, featuring 65 watts RMS per channel into 8 ohms and a distinctive "Natural Sound" design. It is highly regarded for its phono stage, which includes support for both Moving Magnet (MM) and Moving Coil (MC) cartridges. Power and Performance • Power Output: 65 watts per channel into 8\(\Omega \) (stereo). • Frequency Response: 10Hz to 100kHz. • Total Harmonic Distortion (THD): 0.05%. • Damping Factor: 30. • Signal to Noise Ratio: 73dB (MC), 83dB (MM), 100dB (line). [ Inputs and Outputs • Phono Input: Features an MC/MM switch, allowing use with low-output Moving Coil cartridges without a preamp. • Inputs: 2 phono inputs, 2 tape decks, 2 auxiliary. • Speaker Outputs: Supports 3 sets of speakers. Physical Specs • Dimensions: 435 x 337 x 160mm (17.1 x 13.3 x 6.3 inches). • Weight: 12kg (26.5 lbs). Features • Tone Controls: Features custom, flexible tone controls. • Loudness: Includes a unique and usable loudness control that allows for attenuation while keeping low-bass frequencies boosted.
The CA-810 is one of Yamaha’s more desirable Natural Sound integrateds, sitting near the top of its non-Class-A lineup. At US$900, this is a fair-to-slightly-strong asking price: it is above the US$800 median but below the US$974 75th percentile, so not a bargain, though hardly out of line for a properly working example.
Its appeal is real: a clean 65-watt-per-channel amplifier, unusually capable MM/MC phono section, flexible tone and loudness controls, and preamp/main-in connections in a substantial, well-built chassis. It is especially attractive with straightforward 8-ohm speakers. Since the listing gives no condition details, the price makes sense only if all controls, meters, inputs, and both channels work quietly; evidence of recent servicing or excellent original condition would make US$900 easier to justify.
Independent perspective — not a price guarantee. Always verify condition, accessories and provenance before purchase.
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.
