Safety

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.
