Just bitchin here, but wondering if anyone else has the same trouble (?)
A few years ago I bought a MX5050Bii-2 from a guy in CA restored. Anyway, the tape path is very very particular. Running certain 031 reels on it (they are not sticky shed, and record fine on e.g. a Teac 3300) they will almost act like sticky shed or at least oxide shed. The machine will eventually slow down and stop during a fast wind, and you'll find a crap load of oxide residue around the right hand side guide. (Can actually watch it scrape off, almost like peeling a potato or something) It doesn't look (to the naked eye) misaligned, but damn the tolerance must be tight. Same thing happens with non-backcoated Ampex (e.g. 642) oxide sheds like the dickens.
