is your transformer hot with all the tubes pulled? if yes then most probably a bad winding, but what one ? most likely the primary winding witch is the inside winding . best to buy a new one . Take a look at mouser Canada for a Hammond classic 200 series . it will most likly not be worth rewinding as it is not a simple job . if your transformer runs cool with all the tubes pulled then look for a short . hope this helps.
