Plug in the black control box (switch box), transformer and motor. The LED on the switch box will come on. This light will
remain lit all the time that the switch box is plugged in at the mains supply.
The location of the control box should preferably be kept away from strong electromagnetic fields such as those
generated by transformers, amplifiers, power supplies etc.
It is best to unplug the transformer if the switch box is disconnected from it.

NOTE:
You will need to set the motor speed yourself. In the first 4 hours of use from starting up the motor, the speed tends to drift but then settles
down permanently. To burn in the regulator board components we recommend at least 4 hours of running the motor before you accurately
set the speed.
The thin output wires from the transformer only carry 8 volts and are therefore safe to handle. Voltages inside the transformer are
dangerous so the transformer case should not be unscrewed or opened.
When the rotary switch on the control box is turned fully anti-clockwise the motor is off.
One click of the switch clockwise is 33.3 rpm - The second click clockwise is 45rpm
NOTE: The speed should only be finally set or checked with the cartridge dragging on a centre track of a record as the drag
affects speed setting.

Place the strobe disc on the record to be played. Play the record and watch the relevant ring on the disc. Adjust the speed until
marks on the ring appear stationary while the record is rotating. It sometimes helps to stare at infinity whilst doing this as the
marks become easier to see. You can see the strobe effect in florescent light, although an ordinary bulb held about 2 feet from the
strobe disc will also work fine. The bulb flickers at 50 Hz in the EEC and 60 Hz in the USA.
You can purchase bayonet fitting florescent bulbs to fit normal lamps. Try to shut out daylight when carrying out speed setting.

Set the switch on the control box to the first click i.e. 33 rpm setting. Adjust the motor speed as follows: using a small flat
blade screwdriver, turn the screw of P1 for 33 rpm. The screws are accessible at the rear of the control box (See diagram above).
To increase speed, turn the 25 turn presets clockwise until the speed changes. If the screw reaches the end of it’s travel you can
usually hear a faint clicking. You will not damage the preset by over turning it as slippage occurs. The pre-set screw will not fall
out and may need a fair number of turns to set the correct speed so keep turning.
Set P1 so that the platter turns at 33.3rpm. When setting the speed, place the arm on the centre track of a record so that the
