Agree, but just about any tube era transformer will work once set is otherwise fixed, maybe volume might be a little less if large mismatch, but for ordinary radios, no harm in t rying anything you can scrounge up. By the way, since you have nothing to lose, try opening up the "bad" one carefully and see if there is a faulty connection beween the windings and the leads. Happens a lot, easy to fix.
