I bought a sony reel to reel tc353d off ebay i know thats risk taking but It all worked Exept when I Hit recordI it dooesn't record, it just palys back what is on the tape. It Dosn't Erase either. I think it has somthing to with the record head phicly not engaging to hit the tape. Any ideas as to what the probloem is and where in the Philly area i can take the mechine to have it fixed?
