Hi all,

I am trying to repair an old AIWA HS-JX707. It's in pretty bad condition. Apart from the servo motor and belt needing replacing, the flexible flat cable between the tuner circuit board and main circuit board has a few nasty breaks where over the years it has been rubbing against the chassis. Anyone here ever successfully managed to repair one of these cables before?

Have a few AIWA HS-JX707 for part units that have A good cable.

Not impossible....you can bypass broken points with external strands of wire coated with nail polish (to make the 'wires' ultra tiny). Can also make a whole flat connector by sandwiching such 'wires' between cellotape

hi doc P ,,,got a question. i tried getting the coating off the bare wire with everything i could think off. can those tiny wires be soldered without stripping the coating material still on the exterior wire strands. then you could seal them with the fingernail polish once they are soldered. how do you judge what strand or thickness to use or to you just use the old eyeball guess. thanks much

I salvage the strands from normal multistrand wires...take 3 or 4 strands twist them together and then solder them from point to point after which I coat them with nail polish. The normal plastic sleeve insulation is usually too bulky to allow normal closure of the walkman being serviced...

thanks very much...this paragraph is going to stay cemented in my head. it has been a good while since i ran into this problem. it was either a panasonic ktas10 or a panasonic rq-wj1.i never did succeed with either. they ranked right up there with my top 10 disasters. thanks again and take care.
