I bought a very nice almost mint looking T-407 tuner, that appears to be very well taken care of, it was even packed well for shipment!. Every button is still working like new. It pulls in stations that my receivers ignore, but the left channel is dead or down tremendously compared to the right. Seems like it was working a little when I first fired it up, but then it's almost totally dead. If I turn the balance all the way left and crank up the volume, I sometimes can hear it, barely. The right channel sounds better than anything I have here (on FM). I hope I just cracked a solder joint when I pushed on the new RCA cables I bought from Monoprice. They are super hard to get plugged into it. I haven't taken it apart, yet, to see if it's something obvious. It definitely is going in and out of stereo, so that's an improvement over the last one. Does anyone have a schematic for this tuner?
