I can't beleive it. After going on and on about my old reliable 3340 I now have a problem. Channel 4 plays back all previous material but last night when I went to record, it showed normal signal on the VU and the red light lit up but when I played back I got almost no level and could just barely hear what I had done. Like I said, the playback circuit seems fine as all my old stuff sounds great with normal levels. The problem seems to be in the record circuit. The fact that my VU's show level when I'm in source/record mode tells me the inputs are fine. Any ideas?
