    SA-300: Ghost in the machine

    I friend brought me his Fisher SA-300B with a ghost issue. The unit has undergone a full restoration that was done beautifully. All high quality low ESR, power supply caps and super quality film caps for the signal path. The problem happens only occasionally and always on a cold startup. The...

    SA-300 inrush limiter question

    I have a heavily modified SA-300 from a top notch tech in Canada (Sams Audio). The rework is some of the best I've seen. All caps, rectifiers, sockets.. the works all neatly laid out. There issue is the GZ34 rectifier tubes are intermittently sparking on startup. New tubes did not solve the...

    Help Pairing Vintage Technics SA-300 / Alternative to Klipsch Heritage's

    Replacing internal fuse in Technics SA-300 receiver
