Revox TTs really were oddballs. Back in the day, Ernst Benz of then Empire Switzerland was modifying them for the use with MC cartridges, particularly the Empire MC-1000, after hearing one of Revoxes fitted with MC-1000 at an audio show in US and sounding anything like it should have.
Originally, this super light plastic tonearm is meant for high compliance cartridges. It works OK with them. Benz first replaced the injection molded plastic arm with one milled from a solid block of aluminium - better, but not there yet. Next came milling out of solid brass - this was finally a good match with the MC-1000. Benz also treated the ringing platter, etc, etc - bringing out far better sound than usually associated with Revox TTs. Part of the package was also a propriety record clamp.
Revox arm is among the most demanding to adjust for "anything". No VTA, no azimuth, finnicky to the max, nightmare for changing the cartridge, cartridge kit costing way too much back in the day, let alone now, etc, etc.
In operation it is OK if and when playing records that are within tolerances according to the various/combined norms that were in effect back in the day and should have been adhered to to this day. But if and when a record with hole off-cener more than per proposed norm is attempled, it is likely to go completely berserk; sensors for tangency of the servo controlled linear arm movement/angular error operate both for deflection towards inside (all that is normally required ) AND outside. It can fall in the trap of lag, doing EXACTLY the opposite of what it should have been doing - and the sonical result is a complete disaster.
The whole of the original stock Revox TT is THE WORST likely to be found in turntables ever - the structure has more mechanical resonances than their description could stand in a whole page of head-fi. Swiss engineering is generally praised for outstanding achievements, particularly in mechanics - this certainly is among the lowest points in this regard - ever.
