Ok, so this is the super-clean Fostex 80 I recently bought that was damaged during shipping. Aside from some slight cosmetic damage to the front right bottom corner, the machine seems to have survived pretty well considering. The biggest issue is the transport. There are two main concerns. I'm hoping the ATR experts can help me with these.
After testing it, I learned that all the inputs and outputs work fine, they all pass signal well, and all the LEDs in the meter display still work (which was a pleasant surprise).
The take-up reel shaft was so bent that I couldn't even get the reel all the way on. See pictures of this in post #174--titled "New entry into the hall of shame"-- of this thread:

After testing what I could of the transport controls, I learned two things:
1) The supply reel seems to spin fine, but it does the same thing whether I push play or RW: it spins clockwise quickly. I suppose it spins a little faster during RW, but it still seems pretty quick when I push play. I don't know if this is normal or not. When I push play, I would expect it to rotate counter-clockwise at a slower speed (the "play" speed) so that it's feeding tape to the supply reel. Maybe this is not the case if the take-up reel is not allowed to freely spin? Can someone confirm what's supposed to happen to the supply reel when you push play without any tape loaded (but the tape guides are lifted)? See video entitled "Fostex 80 supply reel issue"
2) When I push FF, all I get is a noise, since the take-up reel is not able to spin. So I'm trying to find out exactly which part I need. From the service manual (see attached pages), it looks as though I may just need the part identified as #50, "reel, sub-assy." I haven't seen the back of this part yet, but it looks as though it's secured to the frame --- labeled as number 87 in the diagram but not identified in the parts list --- via three screws. Assuming that frame part is not bent, I don't know what else could be. It's really looking as though the metal shaft part (the part to which the reel clamp attaches) was bent during a fall and that's causing the plastic casing of part #50 to rub against the frame (which I can see), preventing it from spinning freely. See video entitled "Fostex reel assembly issue."
So, my two questions are:
1) Do I possibly have an electrical problem with regards to the supply reel spinning clockwise when I hit play?
2) Can anyone think of/see any other reason for the take-up reel not spinning, or does it seem plausible that if I replace that "reel sub-assy" part, I should be good to go?
Here's the link to the videos:

I really appreciate anyone who can shed some light on this. Thanks for reading!
