Any hope for this little box? It's started playing low on tapes on the right channel. I've cleaned all contacts to no avail. It plays weak when I hook it up via line-out to my hi-fi, too. I'd describe the right channel as missing all highs, as if it had the volume a bit lower and a tone control circuit on it set way down. It plays fine on AUX and the radio. I've tried checking all wires, and I've tapped all the solder joints to see if any are now cold. I know it's a puny box, but I'm already attached to it, and besides, it's hard to get better fidelity and features in such a petite unit.
