I also need it, in the technical service they tell me that the AR8 is discontinued and for this reason they do not have the spare part, the problem is that a year ago (when it was not discontinued) I wrote to them asking for the spare part, and they told me that they did not have it
In short, it is an obvious design problem, due to using bad capacitors, but the users who have trusted in presonus, have been abandoned, we only have to throw our AR8 in the trash
Thanks PreSonus :D
