Note: As of 07/2020 Rosen Sound is no longer providing the acetone strip method for Juno 106 repair! This method worked great from 2012-2018 or so but recently has been quite unreliable as the ceramic substrate begins to deteriorate. Our new service includes brand new substrate replacement chips that involve removing the SMD IC’s from the original 80017A chips and transplanting them to a real PCB.
We believe this is the most authentic method to repairing them, but still also recommend replacements from Analogue Renaissance, which we do not stock. Please let us know if you plan to purchase AR chips and have them sent to us.
Chances are if your Juno 106 (or HS-60, MKS30, GR700) is acting up a bit, you need this service.
Symptoms include missing voices, crackling in the output, no filter control, etc.
Once purchased you will receive a video with instructions on how to remove the module board. It’s really quite easy! Once it’s removed, safely pack it up and ship it over to us.
In about 2-4 weeks, the board will be sent back after a full repair and calibration.
If there are any other issues with the board, we will contact you and discuss how to move forward. In the off chance there is a further problem, it’s probably that one of your DCO’s is bad. We do not charge extra to replace it, however we do require the part to be paid for. You’ll be contacted in that event.
