Any ideas? I just bought this second hand and I was told the only problem was a perished pinch roller. I replaced the pinch roller and fired it up for the first time yesterday and it won't play. It forwards and rewinds and stops without problem. The display is perfect and if I manually roll the tape across the heads the meters register the material but it won't play. I'd like to exhaust all avenues before going back and accusing the guy of selling me a dud. Thanks. Apologies if this is the wrong forum, if it should be in DIY maybe the moderators can move it there? Thanks.
