Roland GP16 effects processor. Now fully working.
We have replaced the original board to board connectors with removable JST headers which facilitates easier removal of either the analogue or digital board for future service (and the original connectors were broken anyway).
PSU has been totally refurbished. +5V regulator, diode and a few other components have been replaced.
It’s currently under soak test and working perfectly.
