I have an old Akai 1720W reel to reel tape recorder, which has worked beautifully for over 40 years. Just yesterday, while playing a tape it stopped, and now it seems the drive motor has a problem. I need to open it up to check for maybe a broken drive belt or a fuse or whatever. I have downloaded a service manual, but it is not very clear as to how to get into the machine. I really need help, as I have some very historic recordings I would like to transfer to CDs. I live in South Africa by the way.
