Powering my OBXa up immediately blows up the tantalum capacitor placed between the IN and GND legs of the -15v 7915 regulator... I also found two partially fried 1ohm fuse resistor on the +15v rail. Any idea what can cause it ? Is there any chance that the transformer is bad ? What is your bet as for the responsbile part ? I uploaded the diagram to the Files section.... any help would be appreciated ! Thanks.
