Hi there. First post on the forum. I've got an issue with my 6200 and was looking for some troubleshooting tips. I've had the amp for a few months and the phono preamp works just fine with my turntable. I recently added a cassette deck and CD player and found that all the other inputs (CD, Aux, etc.) do not work. I use the tape out (RCA to 3.5mm) with a small headphone tube amp and that also works fine. Has anyone encountered this or a similar situation before? Anyone have any tips or advice they could share? Thanks in advance for your assistance!
