Man oh man. I would give up my high end stereo for one of these any day (Even if it is a trade off in sound quality). Hope you have this paired with a similar era loud speaker.My Vintage build.
Those subtle lights, tiny buttons that did something or nothing, all adds to the charm owning one of these.
I owned a Technics SU-800, RS-TR165, SH-8038 paired to a SB-G750 not too long ago. Not to be compared to your gear but reasonably good Hi Fi. Gave it up for the high end world. I sold it for double the price I bought it! You don't hear of this with anything you try and sell today.
Where did you manage to source these components from? We never got Mini Disc in India
