Meluzyna  - the production of the HiFi stereo receiver Meluzyna DST 101  started around 1972. It's price was breath taking: 12000 z³ (140$ or 5 average month salaries), and despite it a crowd of music lovers hurried to buy it, which was very difficult. Nothing strange: "Diora's" menagers admitted in private communication, that their aimed only to show the device at the fairs and get some prizes - production and selling was not considered (who would be fool enough to buy a radio receiver so expensive?).
 In fact, this set was the only one pretending to the High Fidelity level. It was composed of the TST101 tuner, the WST101 amplifier and a pair of loudspeaker boxes..
    It was the multirange receiver: FM stereo range was enhanced with LW, MW (2 bands?!) and SW (3 bands covering 13m - 19m range). It was impossible to switch stereo decoder off in case of weak antenna input. The FM input head was voltage tuned, but station preselection was not provided -  a big wheel with the variable resistor inside was used to change the stations.
 The amplifier was rated with 2 * 20W of RMS output power and was provided with its own measure chart. Headphones output was clearly lacking.
 The two way speaker boxes were equipped with a pair of low-mid loudspeakers and a cone tweeter Audax TW80.
