RECORD CHANGER EASTER EGGS
AND HIDDEN BOMBS

UNDOCUMENTED AND HIDDEN FEATURES AND
PROBLEMS FOUND IN RECORD CHANGERS


Easter eggs are hidden features found in movies, video games, and other media. Some examples of Easter eggs in media are:

  1. In the original Star Wars movie, George Lucas stuck in a plug for his first movie, THX-1138 as the cell number Princess Leia was in on the Death Star.
  2. There was a secret command "PLUGH" in many early Tandy computer games that undid the last move.
  3. Radio Shack Color Computer 3 displays 3 Microware developers after Ctrl+Alt+Reset.
  4. Many Google searches add special images for certain searches.
  5. Many Disney movies have an image of their Mickey Mouse logo hidden in them.

Hidden bombs are places where something bad can happen.

  1. In video games, they are places where the game suddenly quits working or crashes the computer.
  2. Often, using a command in a game at the wrong time sets off the bomb.
  3. Movies don't normally have hidden bombs.
  4. A few movies and TV shows had hidden bombs that activated the Emergency Alert System (EAS) when there was no emergency.
  5. The 1938 radio play "The War of the Worlds" caused many people to panic because they thought the news flashes in the play were real.

In record changers, Easter eggs are hidden functions that are not documented in the instructions or that were not intended to be there and were found to work by user experimentation.

Hidden bombs are cases where things go horribly wrong, or where damage can occur.

To increase the utility of a record changer, I also include some
simple modifications and uses of simple items.

LIST OF RECORD CHANGER EASTER EGGS SORTED BY MANUFACTURER:

BSR
Repeating a record (UA series) Put a rubber band around the size-sensor housing or combined size-sensor/overarm housing.
For normal operation or 7" repeat, leave the rubber band below the record-size sensor slot.
For 10" repeat, place the rubber band so it blocks the sensor about halfway up.
For 12" repeat, place the rubber band so it blocks the sensor near the bottom of the slot.
Put the overarm over the rest post, and start the changer with AUTO.
To stop the repeat action, put the overarm in its low position near the spindle.
When finished with repeat, move the rubber band below the slot.
Repeating a record (100 series) Put the overarm over the rest post, and start the changer with AUTO.
To stop the repeat action, put the overarm in its low position near the spindle.
COLLARO
Manual start near the center of the record (340, 640, 740 pre-1967). Turn off and stop the turntable. Put the record on the turntable.
Move the arm as far as it easily goes inward toward the spindle.
Carefully move it outward just enough to get to the part to be played.
Carefully put the stylus on the record.
Manually start the turntable without turning the control to REJECT.
Adjust spindle for record thickness (Pre-1962 offset spindle). There is a knurled nut directly under the spindle.
Place two examples of the records to be used on the spindle.
Move the record dropping slide toward the spindle until the pusher has raised the record guide all the way.
Adjust knurled nut until record guide is partly inside the top record's hole, but not the bottom record's hole.
Turn nut clockwise (as seen from underneath) for thicker records (e.g. 12" 78, Edison records).
Turn nut anticlockwise for thinner records (e.g. 6" 78, v-discs).
Be sure to return it to standard after playing these records (do with 2 LPs).
Use of 45 spindle was often not documented (pre-1967). Collaro 54, 456, 440, 540, 840, 99 - put the overarm against the edge of the stack.
Collaro 340, 640, 740 - put the overarm on top of the 45 spindle (not on the records).
Collaro Studio 60 - leave overarm over the rest post.
Magnavox manuals for Collaro changers ignore size intermix. Collaro 54, 456, 440, 540, 840, 99 - can intermix 7", 10" and 12" records in any order.
Collaro 340, 640, 740, Studio 60 - Takes odd sizes 12" to 6" in pyramid order (larger records before smaller).
Collaro changers after 1966 - Takes 7", 10" and 12" records in pyramid order (larger records before smaller).
Collaro 340, 640, 740 change cycle There is a neutral position between each pair of speed positions.
The changer will cycle normally even if the speed control is in neutral.
Repeating a record (54, 440, 456, 840, 99) Get a rubber grommet with a 1/4" hole.
Put a rubber band around the record-size-sensor housing.
For normal operation or 7" repeat, leave the rubber band below the size-sensor slot.
For 10" repeat, place the rubber band so it blocks the sensor about halfway up.
For 12" repeat, place the rubber band so it blocks the sensor near the bottom of the slot.
Put the record to be repeated on the turntable.
Put the grommet on the spindle with the top even with the spindle ledge.
Put another record on the spindle resting on the grommet and put the overarm on the record.
Start the changer with START.
To stop the repeat action, stop the changer with STOP.
When finished with repeat, remove the record and grommet and move the rubber band below the slot.
Repeating a record (340, 640, 740, 60, all later) Get a rubber grommet with a 1/4" hole.
Put the record to be repeated on the turntable. Get another record the same size.
Put the grommet on the spindle with the top even with the spindle ledge.
Put the other record on the spindle resting on the grommet and put the overarm on it.
Start the changer with START.
To stop the repeat action, remove the upper record.
When finished with repeat, remove the grommet.
DUAL
1200 series modification prevents playing an empty turntable. Find the part of the Start lever that moves the switch lever on the cam.
Bend it away from the cam and switch lever just enough to miss it.
Changer operation is the same with this modification.
For auto single play, push down the single play spindle during the start cycle.
ELAC MIRACORD
Do not lift the arm from its rest with one finger. Hold the finger lift between thumb and finger.
Otherwise the power switch throws the arm toward the center of the record, causing record scratch.

For 12", Push the drop feeler back away from the spindle.
Raise the overarm and swing it over the rest.
Move the control to REJ and release it
V-M
Tri-O-Matic and Stere-O-Matic
CAUTION - DAMAGE CAN OCCUR DO NOT try to keep the changer from turning the knob to OFF!
DO NOT try to raise or lower the overarm during the change cycle!
DO NOT move the overarm during full manual operation.
All of these can damage the trip slide.
Full Manual Operation Put the record on the turntable.
Put the overarm in its low place next to the spindle and turn the control to REJECT.
The changer will go through a change cycle and shut itself off.
Rotate the turntable backwards two rotations. Leave the overarm in its low place.
Turn the control knob to ON and place the pickup arm on the record.
Do not move the overarm during full manual operation.
Turn the control to REJECT to return the arm to rest and shut off the changer.
Stere-O-Matic
Automatic return to rest after play without shutoff. Move the overarm over the restpost. Then turn then changer ON and place the arm on the record.
At the end of the record, the arm will return to rest without turning off the turntable.
1500
This is the only mini-45 changer with auto shutoff. The arm feels for the presence of the next record before it drops.
1555, 1585, 1701, 1702
Manual play with these changers Put the record up on the spindle and push the MAN key.
The arm feels and lowers the record, but stays poised over it.
If the record is already on the turntable, use you hand to stop the arm when it feels for a record.
Use the CUE key to raise and lower the arm to position it.
Use the STOP key to return the arm to rest and shut off the changer.
WEBCOR
Magic Mind Webcor changers mix 12" and 10" 33 RPM records with 7" 45 RPM records in the same stack. 12" and 10" 45 RPM records and 7" 33 RPM records can be played by turning the speed knob after the arm sets down.
One item that irks some owners is that the speed control turns to 45 after the last 33 RPM record. This is normal, because no large record dropped.
