Before we dive into the schematics, we must respect the machine. The CA-R1 was Yamaha’s flagship integrated amplifier, boasting an unprecedented 160 watts per channel into 8 ohms. Its unique V-FET (Static Induction Transistor) output stage operates very differently than standard bipolar or MOSFET transistors.
