I have a DCC 951 which has always playbacked very well. Today I tried to record something. There was already a recording on the DCC tape and I recorded something over it using the optical input.
During recording the music was coming through the DCC951 over my amplifier, so sound was going into the DCC, however when I played the tape back: nothing. So previous recording was erased, but nothing new had been recorded to the DCC.
I also tried the analog input, and a recording was made and that played fine.
What is going wrong? Recording over anlog works, but optical input just creates a blank tape.
FYI: The DCC player still has the original SMD capacitors.
