Tonkay's right. There's way too much under the bonnet and will require specialist help.
To me, it sounds like the dreaded "orange capacitor disease".
There was a period when Nakamichi used a particular brand of capacitor, (and yes, they were orange in colour), only to find out that some time down the track, they failed.
To localise which particular capacitor it is, you would have to refer to the service manual relative to the FF and RW section, then go through the caps one by one to find the culprit/s.
Not an easy job, and best suited to someone familiar with the ins and outs of these things.
Sorry.....
