Hi, just found your really nice channel!👍 I worked on some of these Revox machnies (Revox G36, A77...). They might look very very nice when they are working, but they are really a pain when it comes to serviceing these devices. Also the Revox-heads tend to wear out faster then the ones of even much much cheaper machines. So yes, really nice to look at, but if you own one, you will be fixing it very often. 😕
