Hey guys, been a while since I've repaired anything but I stumbled onto another big Ben. I've replaced the belts but it still has a playback issue. I can't get the mechanism to lift the tape head assembly. I put up 2 YouTube links for reference. I can take more pics/videos if need be. Any advice will be much appreciated, thanks.
