Roland Juno 106 Service Packages

Roland Juno 106 - sold

Because we work on so many Juno 106s and we get so many people contacting us asking “how much will it cost to fix my Juno?” we’ve developed a couple of comprehensive service packages to address the certain issues we see over and over in Junos and those that all vintage synths share. Typical turnaround times for these standard Juno 106 services are 2 weeks or less!

Juno 106 Essential Service – $280 (parts included)

This package addresses the issues that a Juno 106 is likely to have even if it has been pretty well taken care of, and includes the following:

  • Freshly restored voice cards returned to module board

    Voice chip restoration. Issues of crackling, hanging, intermittent, missing or otherwise nonworking voices are very common and in fact inevitable in the Juno 106. It comes from some combination of capacitance developing in the black resin that coats each 80017A voice chip SMD daughterboard, the SMD solder joints drying out and moisture infiltrating the sand resisters thereof.

What we do: Fortunately, most current voice chip issues can be fixed and their life span can be very substantially improved by a process of carefully and thoroughly removing the black resin coating of each voice chip, re-soldering all of the SMD chips on each and resealing them with a waterproof silicone conformal coating. They will then be installed with new header pins in new sockets on the board so that if they ever have to be removed and worked on in the future, it can be done much more easily. This service package includes full treatment of all six voices. If you have a voice that makes no sound at all before you bring it to us, however, it may not be revived by this process and it may be necessary to purchase a replacement for $40-50.

Patch memory battery replacement – The next step is replacing the soldered-in patch memory battery. We will externally back up whatever patches you may have saved on there now and then restore them once the new battery is in. The new battery will be installed in a battery clip so that when it has to be replaced (in 10-15 years or more) you can just pop it in yourself without having to desolder anything.

Power supply update – As is the case in any synth of this age, it’s time to replace the power supply filter capacitors which are way past their intended life span. In some cases they are even physically leaking alkaline onto the board. We replace them with high-quality, long-lifespan new ones to make the synth less noisy and reduce stress on the circuits that can cause all kinds of problems. We also reflow the solder on the heatsinked transistors and regulators that are susceptible to cracking and causing issues. Optional at no additional cost: Replace Roland power connector with standard IEC power connector so you don’t have to worry about losing your special Roland cable.

Calibration – The final step is to recalibrate the voices, chorus, etc to Roland specs.
If your Juno has only a handful of crackly or jittery faders, cleaning those will also be included in the standard service above at no additional cost, but if your panel controls need more work, we offer the following.


Juno 106 Full Front Panel Service – $120


  • Thorough cleaning of all sliders. 
  • Replacement of ALL tactile (button) switches with new ones
  • Replacement of crumbly slider gaskets with new ones
  • Cleaning all button covers and slider knobs

(If you only have a few bad switches or sliders, some fraction of this can also be done.)

Full Keybed Cleaning for unresponsive keys – $100

Other issues – While these are the most common issues with the Juno 106, these are not the only things that can go wrong in these old synths so get in touch with us and we’ll figure out what your synth needs to get back to sounding as good as new again!
