GENERAL DESCRIPTION

The models ALET and ALETA are 5 volve two hand AC operated table model superheterodynes and features of design include: Tropic-proof construction, automatic of design include: Tropic-proof construction, automatic volume control, magnetite cores in i.r. transionners and broadcast oscillator coil air-dielectric trimming capacitors proadcast oscillator coil, air-dielectric trimming capacitors, straight-line edge lighted dial with metropolitan stations printed in ¹/₈ high characters. Models 804-67 are Radio-Phonograph com-

binations and have similar features.

In addition, the model 804-G incorporates the OAK Automatic Record Changer whilst the model 804-G7 incorporates porates the Garrard RC70 Automatic Changer, features of these being: Permapoint needle plays 2000 records—plays up to ten 10" or 12" (not mixed) records without attention Sucharana mater and simple construction with minimum

of working parts ensures trouble-free service In addition to models 804-G and 804-G7 two further

models in this series have been produced—namely 804-GX and 804.GV

Except for cabinet differences model 804-GX is identical with model 804-GZ, and model 804-GY with model 804-G

The cabinets differ in that models 804 GY and 804 GY have a special record rack built into the side of the cabinet whereas models 804-G and 804-GZ have no record rack

ALIGNMENT PROCEDURE.

Manufacturer's Setting of Adjustments

The receiver is tested by the manufacturer with precision instruments, and all adjusting screws are sealed. Realianment should be necessary only when components in tuned circuits are repaired or replaced or when it is found that the seals over the adjusting screws have been broken.

It is especially important that the adjustments should not be altered unless in association with the correct testing instruments listed below.

Under no circumstances should the plates of the ganged tuning capacitor be bent, as the unit is accurately aligned during manufacture and cannot be readjusted unless by skilled operators using specialised equipment.

For all alignment operations, connect the "low" side of the signal generator to the receiver chassis, and keep the generator output as low as possible to avoid A.V.C. action. Also, keep the volume control in the maximum clockwise position.

Testing Instruments.

A.W.A. Junior Signal Generator, type 2R3911, or A.W.A. Modulated Oscillator, type J6726.

If the modulated oscillator is used, connect a 0.25 megohm non-inductive resistor across the output ter-

minals, and, for short wave alianment, an additional 400 ohms non-inductive resistor in series with the "high" output lead of the instrument.

CONNECTION TO POWER SUPPLY.

The receiver should not be connected to any circuit supplying other than alternating current from 200-260 volts and at the frequency stated on the label within the cabinet. The power supply connections are shown in the accompanying diagrams.

CHASSIS REMOVAL

Model 615-T:

VOLTS

First remove the control knobs-each is held by a set-

rew. The chassis is held in the cabinet by two screws. Remove these and withdraw the chassis from the cabinet

Model 615-TA:

Remove the control knobs from the front of the cabinet -each knob is held by a set-screw.

Pull the knobs from the tuning and tone control spindles. Disconnect the dial pointer from the drive cord, the cable from the loudspeaker, and the dial lamp leads from the chassis

The chassis is held in the cabinet by four mounting bolts. Removal of these enables the chassis to be withdrawn.

Models 804-G. 804-GZ:

First remove the control knobs, which are each held by a

Disconnect, the phono motor, pick-up and loudspeaker cables

The chassis is held in the cabinet by four winged nutstwo at each end of the dial frame assembly. Removal of these enables the chassis to be withdrawn from the cabinet.

DIAL POINTER ADJUSTMENT

Models 615-T. 804-G. 804-GZ:

The dial pointer is held in position on the drive cord by two rubber-lined clips. To alter the position of the pointer, loosen the two holding clips slightly and move the pointer in the required direction. It is important to reclamp the clips after any adjustment of the dial pointer

Model 615-TA:

The dial pointer and drive cord are connected by a thumb-screw. Loosen this, move the pointer in the required direction and retighten the thumb-screw. DRIVE CORD REPLACEMENT

Follow the diagram which is affixed to the back of the dial frame assembly. This shows the route of the cord and the method of attachment.
