Here the deal old spkr is junk unless you can rewind the fc. Fortunately the fc is in the positive leg of the p/s so the resistance isn't super critical. Generally speaking the low the resistance the less inductance more hum. If you have a suitable eletrodynamic spkr then by all means drop it in. Since your set is a console the larger spkr a replacement pm spkr would have some room to mount a choke to replace the fc. For testing purposes a p/p audio output transformer's primary or the HV secondary of a power transformer or choke where just looking for some inductance.
You can replace it with a resistor but it's pretty inefficient as a filter inductance is much better.

I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.

Now I think I've got!
