Installing a 3-Prong AC Jack
Juno-106 control panel

The Roland Juno-106, released in 1984, is one of the most popular vintage analog synthesizers and one of the last to have all its features controlled by dedicated buttons and sliders, making patches quick and easy to program.

The synthesizer has 6-note polyphony, stores 128 patches, and is MIDI equipped.  Digitally controlled oscillators and a fully analog signal path give the Juno-106 pitch stability with analog warmth.

 

2-prong AC inlet

This Juno-106 had a 2-prong AC jack with a broken mounting wing, creating an electrical hazard.

Two-prong, non-polarized AC jacks are obsolete and unavailable.

Matching 2-prong power cords can still be found, but at a premium price.

JKAC48S Installed


With basic soldering skills, it's easy to install a standard, 3-prong jack into a Roland Juno-106.

The jack snaps securely into the rear panel, eliminating the mounting wings and screws.

Any standard computer or instrument AC power cord can now be used.
