The JVC KD-A7 Stereo-cassette-deck with Spectrum Analyser from 1979

Here’s a nice solid and unusual cassettedeck by JVC built in has a spectrum analyser that you probably know from a equalizer on some stereo is for analysing the frequency range optical of your recordings and has no other function. Unfortunality,it’s only a 2 head deck. :-( The spectrum analyser and the . switch,(that nearly worked like an additional “BIAS fine tune“ switch), are the only “special“ features on this looks/works nice! ;-))
