Usually one or more of the diode rectifiers on the chassis short out. This causes the main 8A fuse to blow rather quickly.
I had this happen to two RS35 supplies in the last 6 months. However the main filter capacitor could also be bad. At least that's easy to disconnect and measure with an ohm-meter. The only way to tell for sure is to completely unsolder them and measure all the diodes with an ohm-meter. If anything is open or shorted, replace them. Older supplies will have two stud diodes, others will have two square bridge rectifiers wired in parallel. I found someone on eBay selling 1000V 50A bridge rectifiers for about $5. I used one of these in my last RS35 to replace the pair of 100V 35A bridge rectifiers put in at the factory. So far it's working fine. Easy fix once you have the new parts.
