Vintage Synth Repair

Hi,

The entire Roland service manual for the A-90 controller is posted to
the files area of a different Yahoo group: Roland-Controllers

Once joined, look at the Files/Service Manuals directory.

In the service manual, you will see a description on how to replace
the backup battery.  Recalibration of the pitch bend lever is required
after a battery change - all inside the manual.
