Musser M-55 Vibraphone Motor Replacement and Modifications
This older model Musser M-55 Vibraphone needed a motor replacement. Since the particular model motor that was needed was unavailable, this project involved rewiring a new controller box with all new electronic parts. A mercury switch was replaced with a safer, more reliable toggle switch. In the end, the vibraphone appeared the same as it did before with the addition of a custom made cord wrapper.
DK Percussion Custom Built Vibraphone Motors and Controllers
|Musser M-55 Vibes motor replacement:
Control box was rebuilt to handle newer motor. Notice this control box goes to 11... Actually it should read 0 to 10, since setting "1" is off, or no resonator movement. This is an advantage; no switch needs to be activated during a performance. This was a result of a new potentiometer and motor controller being used. Note the new power toggle switch.
|Musser M-55 mercury power switch:
Old M-55s used a mercury power switch - both unreliable and unsafe. If your control box has a knob for the power supply, you most likely have a mercury switch and should have it replaced immediately.

A new power cord was added to ground the new motor and controller. The old control box was kept in tact.
|Musser M-55 custom cord wrap:
A oak cord wrap was added to the frame for safer storage of the electrical cord. (No more kinks in the cord.)

The new motor required very little modification to the frame.
