Maintenance has been completed, such as replacing 30 capacitors and cleaning volume switch disassembly contacts. Yamaha's famous C-2a. The transparency and three-dimensional effect of the sound have been brilliantly revived. I recommend this one for those who like natural, crisp sound in the mid to high range with good texture. The sound of the PHONO input is good, so it is a popular amplifier for analog fans. The exterior has dullness, bumps, and dirt marks. Serial 04453 (Tamura Eiji) Maintenance information: 2025.6.29 Maintained (power supply voltage drops due to poor EQ circuit transistor EQ circuit transistor replacement. Increased soldering due to poor contact with the MC amplifier. Volume switch disassembly contact cleaning contact grease application. The electrolytic capacitor was replaced due to deterioration.
