No idea. Somebody else here might, so hopefully you get more replies.
I'm mostly replying because:
1. I don't like ignoring posts, hard to have an FAQ with no answers
2. You need to realize that repair parts, or even spare parts deck, may cost more than a better deck.
3. Which brings up the case of why use this deck at all? It's not a highly suggested machine for VHS, due to lacking TBC, and most owners keep it around purely for nostalgia and collecting VCRs (an odd hobby to me, but I don't judge, I collect Smurfs PVCs). It's not bad, and does have nice transport, but not best, and some other with-TBC decks have ice transports too (better SRs).
Just some thoughts.
Good luck on the repairs, I hope you find what you need. (And if you happen to find it, please do post back here, let us know what you did.)
