If the speaker field has been hot it was caused by something drawing too much current. Unless it's open shouldn't need a replacement. Replace filter caps and look for anything else drawing too much current.
The output transformer needs to match push-pull 47 tubes. Only replace it if open. Universal output transformers are available which have taps to match your speaker.
