Maintenance has been completed, including the replacement of a total of 23 deteriorated parts such as transistors and capacitors! This pre-main amplifier was announced as a successor to the SQ505. The lax sound of yesteryear has been inherited, and you can feel the nuance of warm vacuum tubes. The output is modest at 35W, but I feel that it is more powerful than the numerical value. The exterior has scratches and rust spots on the back. Serial 1101800N (Tamura Eiji)
