Someone tried repairing this before .
I have drive signal to all of the power supply fets .
Using the ground pin for the 7915 I get 30 volts on the input pin .
If I install the regulator the voltage on the input pin goes to 8 volts and I never get -15 volts on the output pin most I get is -8 volts .
I replaced the regulator and checked the inductors (47mh) and all test fine I still never get the -15 volts
Any ideas ?
