Fisher Chadwick - Speaker Capacitor Question

I am starting a plan to restore my Fisher Chadwick. It has a 440T tuner, 660A amplifier, and a MPX70 multiplex unit.

The only cap in the speaker circuit is 1.0mfd, 200 volt. See photo.

I was thing of using two .49mfd orange drops in parallel or a 1.0mfd, 250v metalized film cap from Radio Shack.

Any opinions.

The R/S component should work just fine.
