COBRA
DESIGN FEATURES
CONT.
STYLUS RACK ANGLE (SRA) OR
VERTICAL TRACKING ANGLE ADJUSTMENT
(VTA)
Other cartridge sizes can easily be used but the
majority of modern quality cartridge bodies and stylus
tip dimensions are set at or near a nominal dimension of
18mm.
The Cobra arm is very forgiving of setup errors so will
reward those who “seek the tweak” as well as those
listeners who prefer to “set and forget”.
As a general rule if the VTA is too high the sound will be
“lean and thin” and if the VTA is too low the sound will be
“boomy” and potentially “bass heavy”. This is of course
totally to user preference but will reward those seeking the
maximum from their LP collections.
OVERHANG ADJUSTMENT
The best setting is 221.7 mm (set during installation) but
allowance of 12.5mm adjustment in headshell slots allows
some minor variation in this distance. A single 8mm Socket
Head Cap Screw is tightened to lock the main arm support
mount into the correct location allowing for accurate VTA
adjustment without losing settings for overhang.
