I have a 122 Mk. II. I inherited it and a 112 from my Dad's voiceover studio. Over the last couple of years, each of them has developed some problem or another that has made it unusable, but we'll start with the 122, because it's by far the fancier machine, and I used a lot of its features.
I used it usually for transfers from cassette to digital media, so I used it usually every few weeks. The last time I fired it up to use it, as soon as I put in a tape and closed the door, this high speed, high pitch whine started from inside the unit. Not just the usual "motor running" noise. Much louder. When I hit play, the tape appeared to be going, like, 4x speed, way too fast. And no output. The heads don't engage. The speed correction doesn't make any difference at all. On/off, full up/full down, no difference. Obviously the whine was just the first sign that something had failed somewhere. I opened the machine up, and this is a video clip of the sound that the unit makes when a tape is inserted (i.e., that little switch at the top of the tape compartment gets pushed:
The noise is coming from that motor at the bottom with the big flywheel.
So, my question is, what is likely to have failed there? I don't see any place that this particular motor would have driven a belt or anything. The reel motor up top has a belt, and it ffwds and rwds just fine. It's the play transport that's busted. Looking for anywhere to start here.
The other option, are the transport units the same on the 122 and 112, or do they use different units? I ask that because I'm pretty sure the 112 has a broken belt, and I can fix that pretty easily, but if I could "fix" the 122 by swapping in the transport from the 112 (after putting a new belt on it), that would be at least a temporary solution.
Thanks in advance!
