CHASSIS REMOVAL AND INSTALLATION
For convenience and speed in repair work the chassis is so arranged that it may be swung out at right angles to the cabinet, thus providing excellent accessibility.
Disconnect the aerial lead-in, carefully remove cabinet back and lower slightly to enable the aerial on the radiogram to be disconnected.
Remove the bottom right-hand mounting bolt beside the power transformer and loosen the upper right-hand mounting bolt.
Remove all leads from lead guides on the top of the chassis. Swing the chassis out to its stop screw; complete servicing
If the chassis has to be completely removed, proceed as follows-
Disconnect the ultor lead, picture tube socket, yoke plug, mains power plug and speaker plug.
Disconnect the two chassis earth straps from the chassis by loosening their retaining screws.
Remove all the television control knobs on the end of the cabinet; all knobs are a push-on fit.
Remove the control escutcheon by removing the two philips head screws.
Remove the two countersunk screws that are now exposed and remove the aerial lead from the tuner.
Securely holding tuner in left hand, remove the rear mounting self-tapping screw at the earth strap point; gently remove the tuner and control bracket assembly and place it on top of the chassis.
Remove the bottom left-hand pivot bolt and the top lefthand pivot screw and bush, gently remove the tuner and chassis assembly, place it on the floor and remove the TV pilot light from the front baffle. The two "L" shaped notches on the control panel will now locate onto the screw and lug next to the second and third i.f. stages on the valve side of the chassis and, when the screw is tightened, the control bracket assembly will be secured to the chassis with the tuner facing the wiring side.
Chassis installation is the reverse of the above procedure, but make sure of the following points:---
A plain washer must be in position under the chassis for the bottom left-hand pivot bolt.
The yoke, kine and ultor leads must be properly dressed in the two insulated lead guides.
The ultor lead must be replaced in its retainer on the righthand side of the picture tube.
Place the spacing washers (if any were included in the original assembly) in position on the control bracket assembly before re-assembly to the cabinet.
Make sure that the earthing strap is fitted under the rear tuner mounting and connect the side chassis earth strap last
PICTURE TUBE HANDLING AND PRECAUTIONS
Do not install, remove or handle the picture tube in any manner unless shatterproof goggles are worn.
Keep the picture tube away from the body while handling.
PICTURE TUBE REMOVAL AND INSTALLATION
Remove the chassis as described above and also remove the upper left-hand pivoting bracket.
Remove the four mounting bolts, noting that the bottom bolts have cut-down washers and the tuner earth strap is clamped underneath the top left-hand mounting point.
Gently remove and place the picture tube face down on a soft, clean surface.
Loosen the two saddle tension screws and the saddle assembly can be removed from the picture tube.
Loosen the screw securing the yoke clamping ring and remove the yoke assembly.
Installation of picture tube is the reverse of the above procedure, taking note of the following points:---
The top moulded corner spacers are located in the recesses of the cradle assembly and the packing pieces are located on the picture tube adjacent to the saddle tension screws before tensioning the cradle assembly.
Make sure that the picture tube earthing spring is secured across the lower cradle strap.
When viewed from the rear of the cabinet the high voltage contact is on the right-hand side of the picture tube.
When installing in the cabinet, start all mounting bolts in their respective holes; tighten the two lower bolts, making sure that the picture tube is centrally located and firmly pressed against the mask.
Pressing the top of the picture tube cradle assembly so that the picture tube is securely pressed against the top of the mask, tighten the top right-hand mounting bolt, place the tuner earthing strap under the top left-hand mounting and tighten the bolt.
MASK REMOVAL
Remove the chassis and picture tube as above.
The mask is removed by swinging bottom of mask out and removing from cabinet.
Installation is the reverse of the above procedure.
RADIOGRAM
CHASSIS REMOVAL
Disconnect the aerial lead-in, carefully remove the cabinet back and lower slightly to enable the aerial on the radiogram to be disconnected.
Unplug the receiver from the power point, disconnect the speaker, pickup and phono motor cables from the chassis and the indicator and record compartment lamps from the cabinet.
On early models remove the speaker leads from the speakers. The black/white leads go to the speaker on the TV end of the baffle, and for both channels the black lead goes to the + speaker terminal.
On later models remove the five-pin plug carrying the speaker and pilot lamp leads from the chassis.
Remove the three mounting bolts and gently remove the radiogram chassis.
The chassis installation is the reverse of the above procedure.
RECORD CHANGER REMOVAL
Remove the cabinet back as above.
Remove the motor power and pickup input leads from the chassis, remove the screw securing the cable clamp and pass the leads and plugs through the hole into the record changer compartment.
Slide the record changer out until it hits the rubber stops. Remove the rubber stops and then remove the record player and base board assembly.
Turn the unit upside down and two large holes will be observed; through these holes will be seen the clips which secure the record player; compress the springs by hand and swing the clips over so that they are parallel to the screws, align them with the holes in the base board and lift it free.
The record changer installation is the reverse of the above procedure.
DIAL CORD REPLACEMENT
Fig. 1 shows the route of the cord and the method of attachment.
If the pointer has for any reason been dislodged from the guide rail, it will be necessary to remove the front escutcheon which is attached to the chassis by four screws.
FRONT DOOR REMOVAL
The front sliding door may be readily removed from the cabinet by lifting the door up and tilting the base outward to clear the guide rail. Slight downward pressure at the middle of the guide rail may sometimes be necessary if any fouling is noticed.
LUBRICATION OF RECORD CHANGER DRAWER
The sliding mechanism for this drawer consists of a nylon rail protruding from each side wall of the changer compartment and mating with a female strip set into each side of the drawer. Silicone grease or some similar lubricant applied to the relevant surfaces will always ensure a smooth, gliding action.
LAMP REPLACEMENT
It should be carefully noted that both 6 and 12 volt pilot lamps are used in this combination unit. Both indicating lights on the front baffle are 12 volt, while all others are 6 volt.
All lights, except the dial scale and channel indicator lights, are readily accessible on removing the cabinet back. The latter are available on removing the radiogram chassis and TV tuner respectively.
SPEAKER BAFFLE REMOVAL
Remove the cabinet back as before.
Remove the four screws on the upper edge of the baffle (from the rear); the baffle will now tilt forward out of the cabinet.
For all speaker interconnection refer to the speaker wiring diagram on the baffle.
The speaker baffle installation is the reverse of the above procedure.
SPEAKER PHASING
It is essential that speakers are correctly phased. For this reason all speakers have a + mark against one of the voice coil terminals. (This indicates that when a positive voltage is applied to this terminal the cone will move away from the magnet housing.) These phasing marks are indicated on the circuit diagram and on the following speaker wiring diagram.
Fig. 2
MANUFACTURER'S SETTING OF ADJUSTMENTS
The receiver is tested by the manufacturer with precision instruments and all adjusting screws are sealed. Re-alignment 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 specially important that the adjustments should not be altered unless the correct testing instruments, listed below, are used.
Under no circumstances should the plates of the ganged tuning capacitor be bent, as the unit is accurately aligned during manufacture and can only be re-adjusted by skilled operators using special equipment.
For all alignment operations, keep the generator output as low as possible to avoid a.g.c. action. Also keep the volume control in the maximum clockwise position.
TESTING INSTRUMENTS
- (1) Signal Generator, modulated at 400 c.p.s., or
- Modulated Oscillator. If the modulated oscillator is used, connect an 0.22 megohm non-inductive resistor across the output terminals.
- (3) Output Meter—15 ohms impedance.
In order to avoid damage to output valves and associated circuitry when the chassis is being tested, it is necessary to provide a load on both audio amplifiers. Hence a 15 ohms 3 watt resistor should be connected to the voice coil terminals of the amplifier which is not loaded with the output meter.
Set the balance control to the position which gives maximum audio output on the output meter.
Set the volume and treble controls to the maximum clock wise position.
