There are THREE DIFFERENT OILS that Studer/Revox used for their Capstans.
The First is " Mobile DTE extra heavy " Otari also used this oil.
The early Revox and Studer tape recorders used this oil - such as the early A77 and the G 36
This is also a very good general purpose oil !!! The Second is ' Kluber Isoflex PDP65 ' which is a SYNTHETIC oil based on 'ester oil'
This was used in many Revox and Studer capstans - such as the later A77 and B77
and the A-80 and A-800 and A810 and others.
The third oil was the ' Klueber Constant GLY2100 '
a SYNTHETIC fluid specially designed for 'sintered' bushings
Used in the C270 and the A-807 • A-812 • A-820 and A-827 and others.
NOTE: Later versions of the A-820 and A-827 have Ball Bearings and NOT a sintered Bushing. NEVER oil a Ball Bearing capstan !!!
You can find out the kind of Capstan Oil you MUST use by looking at the back
of your capstan - there should be a printed tag there stating which oil to use.
You MUST use ONLY the CORRECT Oil - nothing else !!!
Each Oil is DIFFERENT than the others.
They do NOT mix and Match.
There is NOT One oil that works on all Studer/Revox motors !!!
