ok Mx5050 users or whomever might know, I just bought a used but mint condition unit off the bay. Everything seems to check out very nicely except one thing I cannot figure out. When I record either thru the mic inputs or line inputs I only get the Left channel to record to the tape. The right channel is just being erased by the erase head but not playing anything back. Both VU meters show movement while recording but only the left shows movement and sound upon playback. I also tested the playback head in general with a prerecorded tape and both left and right play fine. I'm assuming I have an issue with just the record head #3. Is it possible these can go bad whereby only one channel is laying down signal? I just find it hard to believe that such an otherwise perfect unit would have such an unusual issue. Am I missing something else?
