One of the finest and best sounding hifi amps made back in 1974 with a class A . Not just a vintage collector's amp, but a main system amp that you can listen to every day with great pleasure and satisfaction. From a time when early solid-state amplifiers in Class B ruled - Yamaha got back to basics with Class A.
Top of line CA-1000 is the first of a very long line of very successful, very reliable and very heavy amplifiers which sold like hotcakes until the mid 1980s : japanese high-end-wise, the CA-1000 is the example everybody else quickly followed.
Two-sided circuit boards, low-noise MC preamp, variable loudness control, switchable Class A / Class AB modes are the rarities which very few other japanese makers had put in their top amplifiers in 1973.
The chassis construction and general layout also was to be a school case of how things would be done afterward : phono stage placed right after the terminals, as far away as possible from the power-supply section, huge 270VA transformer, bigga 18.000µF / 80V capacitors (two), 1% tolerance metal film and styrol resistors, 3-stage DC shelving tone controls, and fully differential with current-mirror power stage driver.
The Class A mode puts 2x 15W into 8 Ohm into your ears, and Class AB up to 2x 70W.
