Well the ROCK pinball has arrived ive been through the marvin guide testing the coils all the rectifiers etc but as for testing the power supply im stuck. Ive tested the 5v supply which is fine but there doesnt seem to be a power supply board for the other voltages? Marvins says about system 80 and 80a but to me it read 80b only uses the 5v supply?
Any ideas?
Plus everyboard in the backbox were brocken of there mounting points id say its been dropped but on a good note there was no battery and no sign of acid damage yipee
System 80b Power supply is not multi purpose. If 5 volts reads ok - then check the other voltages from the transformer board in the cabinet. If you read further on in Clays guide - You will find it there
