So what is the "Panasonic power supply issue"?

That pinch roller is shot. No good. When I worked on those it was routine to replace the pinch roller and other rubber parts, idlers, belts. Often replaced the takeup clutch ass'y too, with OE parts. The aftermarket parts I tried usually came back to haunt me. Another wear part is the back tension band. I can almost guarantee there is excessive back tension on the tape because of a worn tension band. But that will be hard to find new and then you have to adjust the tension with either a special tape with a tension scale or a "Tentelometer" which I used.
