DESCRIPTION OF CYCLE

In order to observe the action of the changer mechanism as it progresses through a complete cycle of operation, disconnect motor plug from power supply so that Turntable can be rotated by hand. Move the front Control Button to the right so that only the word "AUTO" is visible. Then slide the " START REJECT" Control Button to the left as far as it will go and release it. The operation of all parts of the changer can now be examined as the Turntable is rotated clockwise.

SETTING FOR DESIRED RECORD SIZE
1. The position of the 10-12" Control Button determines the size of records that may be played on the changer
2. When this Control Button is in the 12 inch position, the Index Pin (19) is stopped by the front notch on the Index Stop Lever (43). The horizontal motion of the Pick-up Arm (1) is thus stopped. After the Pick-up Arm Lift Pin (17) and Pick-up Arm (1) are lowered, the Pick-up Arm will land in the correct position to start playing a 12 inch record.
3. When the Control Button is in the 10 inch position, the Index Pin (19) is stopped by the rear notch on the Index Stop Lever (43). Since this notch is deeper than the front notch, the Pick-up Arm (1) will be stopped at a point closer to the Center Post. After the Pick-up Arm Lift Pin (17) and Pick-up Arm (1) are lowered, the Pick-up Arm will land in the correct position to start playing a 10 inch record.

SETTING FOR DESIRED NEEDLE
1. Operating the Needle Selector (62) rotates Crystal Cartridge (2) to engage the proper Needle.

DESCRIPTION OF CYCLE (Continued)

TRIPPING To trip mechanism and start change cycle, slide " START REJECT " Control Button down and to the left as far as it will go and then release it.

1. Operating the " START - REJECT � � � Control Button causes the Reject Link (39) to move the Trip Release Assembly (23). This Assembly releases the Starting Pawl (24) and allows the Pawl to engage the Turntable Gear (59) and start the change cycle.

FUNCTION OF THE MAIN CAM (20)

1. The grooves on the upper surface of the Main Cam direct and co-ordinate the motions of the Pick-up Arm Lift Pin (17), which elevates the Pick-up Arm (1) during the change cycle and the Pick-up Arm Follower (18), which moves the Arm horizontally during the change cycle.

DISPLACEMENT OF A RECORD

1. While the Main Cam (20) is turning, the Eccentric (26) turns the Record Support Arms (32) through the action of the Eccentric Arm (27) and Tie Bar (29).

2. During the first half of the change cycle the Record Support Arm Shafts (30 and 31) and Record Support Arms (32) rotate in a clockwise direction. The two lower changer blades eject the bottom record loaded on the changer and the two upper changer blades slide under the remainder of the stack.

3. During the remainder of the cycle, the Record Support Arm Shafts (30 and 31) and Record Support Arms (32) rotate in a counter-clockwise direction. The upper changer blades now slide out from under the stack of records and drop the stack onto the lower changer blades.

MOVEMENT OF PICK - UP ARM

1. As the Main Cam (20) starts to rotate, the Pick-up Arm Lift Pin (17) raises the Pick-up Arm (1) by riding up the outer ridge of the Main Cam (20).

2. After approximately a quarter turn of the Main Cam (20), the Pick-up. Arm Follower (18) enters the groove in the Cam. The groove is cut so as to push the Pick-up Arm Follower (18) and thus the Pick-up Arm (1) to the right.

3. After approximately a three-quarter turn of the Main Cam (20), the groove in the Cam causes the Pick-up Arm Follower (18) and Pick-up Arm (1) to move to the left.

4. Near the end of the cycle, the outer ridge of the Main Cam (20) slopes downward and the Pick-up Arm Lift Pin (17) and Pick-up Arm (1) are lowered.

DESCRIPTION OF CYCLE (Continued)

5. The position at which the Pick-up Arm sets down on a record may be adjusted by means of the Index Screw (41) located on the upper right hand side of the changer base. The Screw acts as an eccentric in.changing the position of the Index Stop Lever (43), A complete description of this method of positioning the Arm and another method which will give greater range of adjustment if required may be found in the " Trouble Shooting Chart under the section entitled "Pick-up Arm (i) sets down at wrong starting point on record".

6. Elevation of the Pick-up Arm is adjusted by turning the Lift Adjusting Screw (5) located on the underside of the Pick-up Arm (1). For complete adjustinent details, see section of " Trouble Shooting Chart "entitled" Pick-up Arm elevation is too high or too low during change cycle ".

COMPLETION OF MAIN CAM CYCLE

1. After one complete revolution of the Main Cam (20), the notch in the teeth of this Cam will disengage the Main Cam from the Turntable Gear (59). The Cam Stop Roller (55) enters a groove on the side of the Main Cam (20) which serves to locate its rest position.

2. The Starting Pawl (24) contacts and again becomes held by the Trip Release Assembly (23).

ACTION OF TRIP MECHANISM AT END OF RECORD

1. During the playing portion of the cycle the Trip Latch (25) contacts the serrated edge of the Trip Release Assembly (23). While the Pick-up Arm (1) is advancing toward the Center Post (53) the Trip Latch (25) will not move this assembly. When the Needle (3) enters the spiral groove at the end of the record, the motion of the Pick-up Arm away from the Center Post will cause the Trip Latch (25) to operate the Trip Release Assembly (23). The Starting Pawl (24) will be released and will engage the Turntable Gear (59) to start the change cycle.

"MANUAL" CONTROL OF CHANGER

1. When " AUTO - MANUAL " Control Button is moved down and to the left so that the word
"MANUAL" is visible, the Starting Pawl (24) is held in such a position as to be unable to engage the Turntable Gear (59) and it is impossible for the changer to cycle automatically. Forward or reverse recordings may now be played by manually placing the Pick-up Arm on the record at the desired starting point.

STOPPING

1. To stop the changer (NOT DURING CHANGE CYCLE), slide the " ON - OFF " Switch (46) to its off position. Power to the Motor (48) will be turned off.

LUBRICATION
The record changer leaves the factory completely lubricated and under normal conditions this lubrication should be sufficient for approximately one year or 1,000 hours of operation. When operated under extreme conditions of dust or heat, lubrication should be performed as frequently as required.

NOTE: AVOID EXCESSIVE LUBRICATION. Do not permit any oil to get on the rubber tire of the Idler Wheel, on the motor hub, on the Trip Release and arting Pawl mechanism, or on the drive rim of the Turntable. Any oil on these places should be removed with Carbon Tetrachloride.

A drop of good machine oil once a year on the Center Post Assembly bearings, motor bearings, small cot ton oil wick on Main Cam, and frictional surfaces will provide the necessary lubrication.
