Reli said:Does the Lasonic have some sort of line-in?
The 915 has no line in or line out. It's a very simple radio.
Should be able to connect a DIN cable to that "REC/PB" jack, insert a blank tape, hit Record/Pause, and use that as your line in.
By the way, a boxed one was sold on Ebay back in 2015, here's the link:

That listing in the first one I ever saw. Never thought I would end up with one, but mine needs a lot of work. New sliders and some other stuff
