Re: Old amp blows fuses with no tubes in: fault of rusty Hmmm... Looks like a dud transformer however again   I would suspect the .05/600volt cap to ground and   would try it without it connected.   I am assuming you are using a 3 pin mains plug thus grounding the chassis via the power (wall) outlet.   Correct me if I'm wrong but in the states it was common to have two pin plugs thus the chassis was referenced to the neutral (cold ? ) via the   capacitor.   Here in Aust (land down under) all fenders   in the old days had a 3 wire Acive,Neutral and earth   power lead fitted often leaving the capacitor wired to a single pole changeover switch which i deduced was to help eliminate buzz or hum coming through the power (crude filter). However as we use 240 volts here the caps sometimes broke down so it was common place to remove them .   Good luck , be carefull and play safe.. !
