Philips
GA212
That Philips
make Hi-Fi of the highest quality as well as good domestic audio equipment is
most clearly demonstrated by the new GA212 „electronic” record deck.
This shows
technological innovation of a high order, resulting in genuinely better
standards of record reproduction.
Its two
speeds (33-1/3, 45 rpm) can be adjusted precisely, using the built-in
stroboscopic rings and fine-speed controls, and are accurately maintained by a
tacho generator that keeps wow and flutter to less than 0,1%.
Speed
selection is by „skin-sensitive” controls that light-up when touched.
Floating
suspensions of the turntable and pick-up arm gives excellent insulation against
shocks and vibration, resulting in very low rumble and very accurate cueing.
Turntable
and pick-up arm have been mounted on a sub-chassis which is suspended from the
rigidly mounted main chassis. Considerably more flexible springs can therefore
be used. And as the motor is independently mounted underneath the main chassis,
the pick-up arm is doubly insultated against vibrations from the motor.
the tracking
error of the virtually frictionless low-resonance pick-up arm is exceptionally
low. Side-thrust may be compensated at all playing weights for both conical and
elliptical styli.
The Philips
slide-in carrier accepts virtually any pick-up cartridge with fixing centres to
the 1/2” international standard. A Philips GP400 Super M magneto-dynamic
cartridge is supplied.
Switching on
and off is done silently through a bi-stable multi-vibrator, operated by
relay-type switches.
Autostop at
the end of a record is not effected by mechanical means, but electronically.
When the rate of interception of a ligh-beam striking a photo-sensitive cadmium
sulphide cell exceeds a certain value, a bi-stable multivibrator is triggered,
cutting off the motor supply voltage. Hence „thumping” and groove jumping
cannot occur. The pick-up can be lowered precisely into any groove, even close
to the run-out, without premature switch-off.
