Hello all! This is my first time on this forum.
Just today I found an abandoned boombox next to the trash collection bins and decided to take it home with me. It's a Hitachi TRK-7800E. On the outside it looks fine, just a little dusty. The power cable works and the antenna picks up radio on FM. However the audio crackles a lot and loudly when using the controls, and the speakers use a different level of volume on each off/on switch and occasionally only use either of the two speakers, but both do work. I suspect the speakers have a loose cable inside?
It would be wonderful to restore this old boombox! My technical experience is limited to woodworks in primary school, although we did do some wire welding there and made some battery powers cars and boats :) So where should I start and what do I need to know?
