Alright, so I found an RX-C39 for a steal a while ago.
It's been working really well, so now I don't have to worry about ruining my tapes in a disgusting cheap-o cassette player.
Only problem that I can't find a solution to is the fact that it cannot record to a blank tape.
I don't really have a way to get a manual at the moment, so it might just be best for me to wait until I can; but I figured I'd check here to see if anyone has a solution.
Looking in the machine, it seems like there's a large white plastic... thing, like a large lever, and it's blocking the record mechanism. All I get is a soft whirr from the motor; the tape doesn't spin, nothing happens. I'm not sure what the purpose of that white piece is, or if it just won't accept a line-in to record, but it's a little frustrating to say the least.
If anyone has some suggestions or info, that would be amazing!
