still having issues with the 909? Of the three you mentioned I honestly think the ReVox is in it's own league. Parts are readily available, they simple to work on (not by me though) and they were built to take a lot of abuse. Of my three, Teac, Akai (top of line Akai) and ReVox, the ReVox is definitely the best sounding. Of course this is my opinion which counting for inflation is still only worth a few cents. I do have experience using reel to reel tape decks continuously since 1970.
