Also keep in mind that the open driver transformer primary winding may not be the cause of you having no sound at all. If the other half of the primary is still good, then one of the 6J5 drivers will have plate voltage and will provide some audio signal to the output stage. The radio should still play to some extent, but maybe not at full volume.

Do you have voltage on the 6J5 plate connected to the good winding which measures 217 ohms?
