A 300 W monoblock from 1975 - the unit that made Accuphase's name in professional and studio installations.
Mains-powered vintage Accuphase: the big filter capacitors and the bias network need checking before first power-up, and the original Sanken/MOS-FET output devices are unobtainable. Japanese-market units may carry a 100 V transformer with a voltage selector - confirm the setting before plugging in.
Marks that can be entered for this maker: Model / catalogue number, Model / catalogue number, British capacitor code (Hunts, Mullard), Japanese capacitor code (Nichicon, Chemi-Con, ELNA), EIA component code, Version & era marker.
Nothing predates 1975; components only push the date later.
