Hello, I've a problem with my Seeburg EPFEAI (exportmodel). When I make a selection the substractcoil remains energized, resulting in a loud buzzing. It wil play however the correct record. I can only stop it by turning the machine off. I've cleaned all the contacts in the pricing unit and electrical selector. Touching the contactplate of the timing relay in the pricing unit resets it. Should it work that way? I mean, when making a selection, the timing relay releases after a while the substract coil? I'm kinda stuck on this... I have the manual, but unfortunately it doesn't help me this time. It has only the schematic for the UDPU4. The pricing unit this one uses is the DPU3, but I don't have the schematic for that. The timing relay is good. Can anybody help me? Kind regards, Jurjen
