I am using this Yamaha CA-810 Integrated amplifier to power the JBL L60T loudspeakers described in a previous post. Built from 1977 to 1979. A heavy amp with a conservative rating of 75 watts per channel. While the amp was being reconditioned, I was told by the service tech that this amp easily produced more wattage than its specified rating without breaking a sweat.
Typical of well-built integrated amps of the 70’s, it contains top shelf interior components and a well thought-out design. It has a unique and useable loudness control which allows you to attenuate from any main volume setting while still keeping the lower bass frequencies boosted. It also has a great phono section for those still spinning vinyl.
All switches and knobs have a robust feel and, no doubt, have great build quality. These amps, if properly maintained and serviced, will truly last indefinitely. Pair this with any input source, be it analog or digital, and you will have a fantastic system.
