There is nothing wrong to use a 300B to test a 300B transformer. And it is even better because you directly have the right bias and the right pre-magnetisation for the transformer.
For PP transformer it is better to use a variac (or on the primary or on the secondary). A ss can be broke if the transformer saturates.
