Hi all, I just picked up a portaone off ebay, the problem is that when there no tape inserted all the functions seem to work perfectly. when i put a tape in though, the record/play function doesn't work right. The speed of the right reel is slow and sometimes stops sporadically. this causes the tape to get loose inside the cassette. REW/FF work fine with a tape in though. any ideas? low voltage? belts? bad motor? thanks for the help.
I think that FF and REW are based in a clutch whell ... capstan and take up reel in belts instead. If belts are parked a long time (years?) ... now are deformed, abrasive are losted ... and it slips Sorry for my bad english.
shure it's a mechanical problem. Look the belts and replace if see any deformation. Look the clutchs whells rubbers. If contact surface are shinning and/or polished the contact slip. The rubber must be abrasive. Clean it. Warning-caution-atention: do not use alcohol. (may be neutral soap) After, you can lubricate the whells rods whith a litle-litle-litle bit of spindle oil . Warning-caution-atention: do not sully the rubber. good luck! don't loose any screw! Sorry for my bad english
