If the PT-25 is the set shown in your profile picture then the chassis in those are rather cramped to work on. They stuffed a typical five tube AC/DC set into a chassis that is about 6''X3'' and with almost zero room inside the cabinet to vent the heat out. I know that the usual warnings say not to play it but about the worst that will happen is that the rectifier tube may burn out, there is no power transformer, however it likely won't be very reliable over the long term. I think getting in touch with the radio club may be a good idea, the only guy I know of in the Chicago area who services sets for people is Bob Andersen, but he does not do it as a business and is usually busy working on his own sets.
