Thanks for that. Where do you recon I should start trouble shooting the Output Loop. My receiver is strange that where
you select am or fm it uses .5khz filter even thou there is a 8kHz filter, and can select it using BW
I had a look on murphys site could not find any cubic stuff, and he will not export anything even nonmilitary.

        Check the bridge if the one on the DC side is blown. It usually takes a diode or two with it.
        The bridge makes plus and minus 135 volts and the switcher primary side is referenced to   -135. Murphy has a 3030 power supply. frank

          Hello Everyone

          Well I managed to blow the side off a component in my power supply. I have have never used one these before.
          There are two of them, one across the ac input the  other across dc side of the bridge rectifer. This CR12
          right under switch S1 What is it? I need to replace it and I don't know what to order. Is this what they use in place of a fuse?
          Why didn't they have a fuse?
