I met up with a very talented lazer engineer called Graham last year and we chatted about our mutual interest in tape recorders. Probably not realising what he let himself in for, he is now well into refurbishing our Revox B77. We bought a kit from Australia which has all the components you need to bring the machine back to essentially brand new. Then I managed to get brand new hears from a guy in Romania. Sounds sketchy but the guy came up trumps and they duly arrived in the post.
So a month or so in and Graham has disassembled the motors, replaced the bearings and things are looking good so far. If you haven't spent enough time today checking out pictures of shafts and bearings then here's your chance.
