Refreshed and maintained, including volume switch disassembly, contact polishing, 43 transistor and capacitor meter replacements, etc. 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. Serial 03044 (Takasaki Atsushi)
