One of my latest arrivals - the Toshiba RT-SW7 from the "SUGAR" series.

It came as usual, dirty, tape decks not working, crackling sound with low volume. Fortunately, these pieces are easy to maintain. The cassette mechanism is easy to remove and change of belts is no problem. Tape speed could be adjusted with alignment potentiometers on the main board.
I cleaned the volume and tone potentiometers with tuner spray and after one night the sound came back without noise and with full volume.
At the end some polishing on the outside and now it is my SUGAR :-D

After I had the RT-SW7 prepared, I have seen, that there was a similar piece of “Sugar” available in the eighties – the RT-SW9. I was thinking, I should have one for my collection. So I got a very cheap piece from Japan, declared as junk.
My first impression was, that it seems to be really junk. It was completely dirty, filled with dust bunnies, no sound and the tone sliders could not be moved. And, of course, tape was not working.

Started a deep cleaning and applied a new belt. For the volume potentiometer and the tone sliders I used again the tuner spray. This is magic! After one night the sound came back and the sliders could be moved again. Not very smooth, but usable.
These boomboxes seem to have a quite robust mechanic and electronic. FM radio works without problems and also the tape deck is fine, including auto reverse. No azimuth adjustment was needed, only speed adjustment.

Now this is the new friend of RT-SW7.

Interesting thing is, that the RT-SW9 was cheaper then the RT-SW7, although in my opinion the SW9 has the better sound adjustment with 3 sliders.

I am always amazed at the tape technology applied to these boxes. Logic and autoreverse. Wow! Good for you! Enjoy it. You did a fantastic job cleaning it up
