Will transformers from a Fisher using 7591 tubes work in a Fisher 400 that uses 7868 tubes?

Thanks,
Mike

Yes, however the feedback circuit may be a little off depending upon the original Fisher 400 transformers. No big deal to me, but I would look at it. Others may have more to say about it.

You see, two different audio transformers were used in Fisher 400 receivers. One type in later Fisher 400s is around 10K primary & other I guess around 7K primary impedance in early Fisher 400s.
