*Unsolved* Virus B Rack with no power
 

Hi everyone.



I currently have a Virus B rack mount which has no power. I have checked in the power supply and I seem to be getting a very noisy 12v line going into the 5 pin 5v regulator. I swapped that reg for a known working one and still no luck. I noticed the supply turns noisy after it has passed through one of the coils. I replaced the two 100uf capacitors previously mentioned on here and still no luck.



In order to carry on I could really use a proper schematic. I have tried contacting their service centre in Germany and still no luck.



Anyone have any useful pointers or even a full schematic here?



Kind Regards
