    Hallo there,
    I just registered to this forum because I have a problem with my Tascam 688 and i hope that somebody can help me fix it.

    The Tascam 688 makes a weird humming noise when turned on - and the tape slows down and stops after I hit play. I made a video of it:




    I would like to repair it of course:)
    Do I just need a new capstan belt or actually a new motor?
    Or is something else broken?

    Greetings,
    Panane

    Hey.. Hard to say on that but there is a guy on youtube (might even be on here..) named Tetrakan Supermonobloc. He does tear downs of alot of portastudios and they are beyond helpfull. I would watch the 688 one if its there and have a look around, and at the transport mostly. Might be a belt or a gear/motor..
