72 deteriorated parts were replaced in 2023/7 and a thorough overhaul was carried out! A pre-main amplifier that was released in the early 70s and features a sophisticated black panel. It is an amplifier that has a sense of power for its output value and has a good balance between the sense of extrusion and bass in the mid-range. Dull and in good condition for the model year.

Maintenance information: 2023.7.31 Maintained (some 20 electrolytic capacitors and 48 transistors replaced. Output relays, fuses, rectifier diodes, and film capacitors have been replaced, lever SW disassembly contacts have been refined, and grease has been applied to prevent oxidation and sulfidation. Circuit readjustment, input/output waveform confirmation, load test (1 kHz sine wave, 8Ω load: 64W+64W, OK), sound output test) 2018.10.10 maintained (electrolytic capacitor, relay, SP terminal, RCA terminal, transistor, semi-fixed resistor, fuse replacement. Contact cleaning and protective agent application. All boards are re-soldered after removing old solder. Various adjustments, input/output, volume operation, waveform confirmation, input/output waveform confirmation, load test)
