Philco 91 Speaker Replacement
#13

As Rod said, it is OK to use a fitting speaker, and then look for an original one.

If you buy a Hammond 125 output transformer, you could use just about any speaker and simply match the impedance by using the respective secondary taps of the 125.
If the field coil is too much, you can bypass it by paralleling a resistance; if too low, you put a serial resistance.
If you have a Philco speaker with the good transformer, make sure it is for P-P and the primary reflected impedance fits your output.

This said, if your speaker's field is good, send it for re-cone: you will have an original speaker with a new better cone. And it is not too bad price-wise. Sound Remedy in NJ, Rich Stamer, he does excellent job.
Of course, if your field coil is bad, then....

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
