After replacement of the pickup cartridge or stylus assembly,
the stylus pressure should be checked and the counterweight
readjusted if
necessary (see page
7).
The SP 10 A pickup is separately available for use with the BEO
GRAM 1200. The SP 10 A has a nude diamond 15-micron stylus
tip and features high-compliance suspension, permitting reduct
ion of the stylus pressure to 1
-
1.3 grammes (maximum 1.5 gram
mes), The SP 10 A will give you wider tonal range and better ste
reo reproduction.
The SP 12 A pickup features the same type of high-~ompIiance
stylus suspension and the same stylus pressure as the SP 10 A
but uses a nude diamond 5 X 17 micron elliptical stylus tip. Us-
ing the SP 12 A you will obtain even lower distortion in the
treble range.
The automatic movement of the pickup arm from the rest posi
tion to the playing position is factory pre-set for the mean value
of conventional record sizes.
If the pickup of your BEOGRAM 1200 does not hit the first
groove of your records you can have your dealer perform the re
quired adjustment.
However, you can make the adjustment yourself, using a thin
screwdriver.
If you set the pickup arm between the size of a 17 cm (7 in.) rec
ord and that of a 25cm (10 in.) record, the adjustment screw
will be accessible through a hole in the cabinet as shown by the
sketch.
Turning the screw clockwise will cause the pickup to be lowered
farther in on the record. Turning it anti-clockwise will cause the
pickup to be lowered farther out.
NOTE: Normally, the screw only has to be turned less than a
quarter turn. It may be necessary to repeat the adjustment.
