Garrard 401, Инструкция по эксплуатации, Страница: 11 / 21

Power Supply Frequency
If this is altered, say from 50 c/s to 60 c/s, it will be necessary to fit the alterna-
tive motor pulley and turntable, both of which are available from our Spares
Department and referred to in the spares list at the end of this manual.
To fit the pulley, remove the turntable, slacken the three small screws at the bot-
tom of the stepped pulley and lift the pulley off the motor spindle. Do not con-
fuse this collar with that on the aluminium brake disc below the pulley. Fit the
replacement pulley after checking its identification; brass for 60 c/s and partial
nickel plate for 50 c/s, then after checking its position re-tighten the three
screws equally. The operating frequency for the stroboscopic marking on the
turntable, in cycles per second, is stamped on its underside. This will be either
50 or 60.
Finally it will probably be necessary to make the adjustments mentioned under
the heading 'Turntable Speed'.
Model 401 Neon Lamp
Note that Model 401 may be fitted with a neon lamp other than that referred
to in the text, line diagrams and parts list of this booklet This lamp is fitted
across the front of the unit, illuminating the stroboscopic turntable directly,
as in the photograph on page 3 and it is wired so that it is suitable for both
110/125 and 220/250 AC voltage ranges. See page 20.
