Drive belt whine

My 1993 900 2.1 recently had belt squealing, which, at about 80000km (50000 miles) resulted in a new harmonic damper drive pully being installed.
I suspect that this was overkill, but regardless, the net after effect was a turbine-like whine "chee-chee-chee" pulsation at 2900rpm in all gears.
Several attempts at various belt adjustments, and even twin belt replacement (all belts had been replaced)did nothing. Tightning made the whine worse. Eventually I had the bushings on the alternator (all bearings were fine) replaced in order to align it more precisely with the driveline.
I was told this was common due to the 900 alternator mounting style. I have owned 3 900's, and this is the first occurance for me.
Anyway, I have just driven it home, and the problem is much improved, but still detectable.
Anyone got comments on this, because it was driving me nuts. I love my 900, and it is in mint condition, but if this problem comes back, I will hate to drive it.
Thanks, and please reply to arnold_broese at hotmail.com if you have any ideas.
Cheers.
