Revox A77 mk2

@cwz have you tried rebuilding them? I've had a number of Ampex, Revox, Magnacord and other machines with noisy bearings but I've never had to replace one of them; I simply made sure they were properly lubricated.

Thanks atmasphere!

Good suggestion! I've thought of that also but didn't know what type/weight of lubricant to use! I assume one can pry out the covers and press lube into the bearing similar to repacking a wheel bearing on my old vintage Porsche!!

Have you searched @ tapeheads.net (regarding the correct grease)?

Not yet!

Right now I can't figure out how to get the endcaps off a 608zz bearing in order to re-lube it. Looks like they were never intended to be removed.  Maybe the capstan shaft needs to be re-lubed? I recall a warranty repair in 1971 in which Revox service in Nashville replaced a "noisy" original 608zz (SKF made in Italy). I'm wondering if shaft end-play or the sintered bearing in the housing is the problem!

The SKF and other quality bearings of that style and size are available on Amazon.
