This set will require a tuner to enable the heaters, thats assuming the tuner has valves, looking at the set I would say that's likely. You can bridge the heater pins (temporarily) to enable you to check the rest of the set. I would imagine you are going to have a lot of faults. Indeed pumping mains into it is not recommended, it will want waking up carefully. Methods of doing this will no doubt, will be on this site.
