Victor (JVC) HV-VMD1 MUSE Decoder and M-N Converter

Mass of this unit is 4.7 kg.

The main circuit board is very simple compared to, for instance, the roughly contemporary Sony MSC-3000, and there is only a single oscillator crystal, 32.4 MHz. While frequency synthesis is certainly possible, there is some reason to think that decoding is not performed to full specification.
