SERVICE AND ALIGNMENT INSTRUCTIONS

To service this receiver it is first necessary to remove the motorboard with the record changer and then remove the chassis through the top opening of the cabinet. To lift the entire motorboard with the changer, unfasten the six screws holding the motorboard in place, disconnect motor and pick-up plugs from chassis, and lift up. It is unnecessary to remove ne screws holding the metal shield in front. CAUTION: WHEN REMOVING THE CHANGER BE RE TO PLACE IT IN A POSITION WHEREBY THE CHANGER MECHANISM WILL NOT BE DAMAGED.

ALIGNMENT
Equipment Required: Modulated r-f signal generator; output meter; insulated screw driver; one I mfd 400 volts and one 50 mmfd 400 volts condenser.
With the receiver removed from the cabinet, connect output meter across voice coil. Connect ground side of the signal generator to chassis; tur volume control fully on, and keeping the output of the signal generator as low as possible, proceed in the sequence as shown on the alignment chart.
To facilitate alignment of the receiver when removed from cabinet, calibration points are provided on the pointer slide bar (soe drawing).

Before aligning, close the variable condenser fully counterclockwise (plates fully closed) and check that pointer carriago coincides with the " reference line " on the pointer slide bar.

REPLACEMENT PARTS

SERVICE AND ALIGNMENT INSTRUCTIONS
WHEN SERVICING THIS RECEIVER DO NOT PLACE CHASSIS ON A GROUNDED METALLIC BENCH.
For tube replacement it is not necessary to remove the chassis from the cabinet. Access to the tubos may be made by removing the center screw on the loop holding same to the bracket, and then lifting loop carefully off the bracket to as to avoid breaking of wires connecting sume.
For ALIGNMENT the chassis must be removed from case. Remove first batteries and then the three screws holding chassis to the bottom of the shelf.

ALIGNMENT
Equipment Required: Modulated of signal generator: output motor; insulated screw driver; two.I mfd 400 volt and one 50 mmfd 400 volt condensers.
Turn variable condenser fully counterclockwise (plates fully closed) and check that pointer coincides with the first thin calibration mark on the dial. Connect the output meter and signal generator as follows: Output meter: Connect across voice coil and turn volume control to maximum. Signal generator: Connect the low side of the signal generator to the receiver chassis thru s I mid con denser and keep output as low as possible, then proceed in the sequence shown on the alignment chart.
