Ron do you work on the later rockola's? I ahte my box an it is about ready to be shipped to the land filed no one wants to work on it. Charlie Maier was to last to service this darn thing. UGH His words on the phone about this box was not good. This was the first rockola to use a computer an boy did they not work things out.
Problem with it now is the amp. It was rebuilt by Charlie along with the logic board. I think the amp has a bad driver board on the left side. Also the darn thing forgets what it was doing in will lose all the selections in memory. Service guide is a joke on that one says to replace logic board.
