Hi, can any one tell me where I can find the schematic for the Z3801a Power supply board? My Z8301a now refuses to start up. All the pico fuses are intact and there is obvious signs of overheating/damge. There is a connection between the power input +ve supply and both the DC/DC converters but there is no connection betweenthe -ve and DC/DC converters - hence no output voltages anywhere! I remember reading on the forum that there is a pre-regulator between the Power input and DC/DC converters, so I'm guessing that is where the problem lies, but without a schematic it's going to be hard to locate a fault. Any help appreciated 73 Richard G3VZG _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
