THORENS TD 550 - Manual (Page 34)

Adjusting tonearm height (VTA)
If your TD 550 has come factory-equipped with tonearm
you may disregard the following instructions.
VTA adjustment is as different as there are different to-
nearms. However Thorens can supply a special clamp
mechanism for tonearms without the facility of adjusting
VTA (e.g. Rega).
ATTENTION: great care is necessary for the fol-
lowing mounting and adjustment procedures, be-
cause the slightest mistake can damage stylus
and cantilever!
Make sure the tonearm has been completely mounted.
Carefully detach stylus guard from cartridge. Put (an old)
record on the platter and lower cartridge onto record. The
tonearm tube should then be parallel to the record (to be
viewed from the side). If this is not the case VTA (Verti-
cal Tracking Angle) needs to be adjusted by altering the
tonearm height.
