Got this one, to my surprise, in near mint condition, at a price that made me expect a "for parts". It has no scratch or marks on any of it (many) aluminum surfaces...
Only had to remove a little bit of dust from behind its speaker grills, it even had been rebelted.... Switched out 1 tape button, the play button has the slightest bit of its chromed surface bubbling...
Originally bought it to restore another one I have but with a lot of issues...
Only did 1 thing on it : adding Bluetooth...
Made a Led-holder out of plastic sheeting so it was "easy" to fit behind the tuner window without having to remove anything, and so it has the same look and design the other leds (power, tuned, detuned, stereo) have, not to mess with the original design, added a multifunction metal button in the dip next to the antennas to keep it discreet.
Bluetooth is powered by a mains to usb (its a usb module), connected to the mains of the device - button and led are deported from the original bluetooth module pcb , I added a resistance to the blue led, so it was more in accordance to the light intensity of the original tuner and power leds. When bluetooth is off, led is off.
