Summary

AUTOMATIC CHANGER OPERATION

Change Cycle Mechanism

The changer uses a 'Velocity Trip' mechanism initiated by the pick-up arm's inward motion as the record plays.

Cycle Triggering

When the stylus hits the lead-out groove, the Striker Feed Lever's velocity moves the Striker Arm to trigger the mechanism.

Automatic Shut-Off Function

The changer automatically stops after the last record plays, initiated by the Main Cam Gear engaging the Shut-Off Lever.

Speed Change Mechanism
