    Default FS - Toshiba ST-420 FM/AM tuner

    Here for sale is my wonderful Toshiba ST-420 tuner.

    I just don’t have the room at present to keep this beast.

    First produced in 1977, it has superb battleship build quality partnered with a gloriously big, full sound signature.

    Signal and tuning meters work perfectly, as does the monster weighted tuning knob which is a joy to use. All the bulbs function correctly.

    Condition is very good for its age with a few scratches and scuffs, mainly to the grey paint on top.

    Dimensions -

    W - 45cm
    D - 35cm
    H - 15cm

    £90 cash on collection or ppl gift, from Highgate N6.

    I have taken the following info from the fmtunerinfo.com website -

    "The ST-420 is a well-built, made in Japan, analog, phase locked loop, AM/FM tuner. It has an FET-based front end composed of 4 FM gangs and 2 AM gangs. The IF strip includes 3 three-legged ceramic filters, 1 SFE10.7MA and 2 SFA10.7MCs, feeding discrete components into a ratio detector. MPX services are provided through a Sanyo LA3350 (one of the few ICs) and then once again into a discrete audio stage with buffer. The front panel houses a power button, signal and tuning meters, and controls for output level, recording level, FM mute and band selection, with the muting switch separate from the FM Stereo/Mono switch. The tuning knob is big, weighted and silky smooth. The dial scale stretches across the full width of the tuner with the band and stereo indicators located at the high end of the scale. The back panel has the usual antenna attaching points, fixed, variable, and MPX/scope RCA outputs, a 25/50/75µs de-emphasis switch and an AC outlet. Inside, the tuner is well laid out with the tuning cap isolated from the main system board. A fully removable bottom panel makes access to the boards fast and easy. This is a very quiet, good-sounding unit with lots of potential for mods. It handles the HD nasties very nicely, a plus nowadays. Although it’s already a pretty good sounder in stock form, after removal of the two ceramic caps directly in the audio signal path things get immediately and immensely better."

    I will be in Manchester next Tuesday (24th) and could bring the tuner with me if anyone would like to collect from M20.
