[Premium-Rx] CUBIC-CDR-3250-LF-HF-DSP-COMMUNICATION-RECEIVER

Can't help with a schematic, but just repaired a friend's Cubic 3280 last week ... with the same 
problem. As is often the case with switching power supplies, an electrolytic capacitor was the 
problem. IIRC it was the 220uF/35v but replaced all of them while it was apart.
