Revox A77 mk2

Replace the bearing? Actually, you might want an expert to fully service it, that's a great machine. 

great machine! replace and consider a spare….

I've already replaced bearings several time over the 50+ years I've had the Revox. My source of replacements may not be the best. If anyone has had good experience acquiring "quiet" bearings, I'd appreciate to know the correct p/n and source.

Thanks
