It's normally a slower wow.
3-4 times per second is more like a vibrato as you suggest and I would suspect
the capstan itself, dirty or bent.

If the source of wow is the belt, how does it sound like? My BC9000 has the issue, I can't seem to find the thing causing it... It is altering speed (up and down) about 3-4 times a second, it sounds like a subtle vibrato. The deviation is not that great, it is not over 5% I think.

Please note that not only the size but also elasticity needs to be correct. It's particularly important in
these decks with motors using sintered bronze bearings and a sideways pull to the pulley. With a too low
elasticity the poreus bearings will wear down at an alarming speed and new motors are no longer available.
I've seen a couple of cases where off-the-shelf types has been mounted and I have a couple of bad
motors lying around with bearings that had their bearings worn to the point
of blocking the spindle with burned commutators and coils as the result.
If you need it, I can supply correct belts, produced to a slightly narrower width to also guarantee that the capstan
belt doesn't rub on the support plate which can be an annoying and very difficult to diagnose source of wow.
Mounting instructions with photos and english text can be included.
