![]() ![]() One problem you may experience, because you don't have the old Behringer power supply you won't have the quick disconnect cable from the PS to the mixer which has the color coded wires. Nick, attached are pic's of the individual power supplies, pic's of their part numbers and a hand drawn pictorial of how to hook the stuff up. I have not been able to resolve the problem.Īlso, the AC input voltages from the transformer to the PS board are present and correct. I have replaced various newly install components (like the Cap's, Diodes and LM388T's) with other new components thinking maybe a new component might have been bad but so far. ![]() I'm thinking the +17 on the bad PS drops out once a load is put on it but I don't have the knowledge to understand what component might be causing the problem. I have two MX9000 mixers with one good PS so I am able connect the good PS to either mixer and the +17 is present. ![]() I have also checked to be certain there is not a loose and intermittent connection at the pin-out. The PS shows correct voltages of -17, +17, +48, +12 & +5 at the PS pin- out but when connected to the mixer, the +17 is absent. I replaced all three LM350's with LM388T's, as well as replaced all of the Cap, Diodes, resistors and the LM317 and LM7818 power transistors. I have a Behringer MX9000 400 Watt Power Supply which did what most of them do. ![]()
