Silvertone here it's a 10 inch PM type Primary impedence (not resistance) should be 5,000.
The loctal output tube 7C5 is similar to the octal 6V6.
More tube information here:

There are methods to determine what the secondary impedence (not resistance) for you to google, but most likely an efficient 8 ohm speaker would be fine. Do nopt operate the set without a speaker.
More info on the Silvertone here:

IF can wire size and Rubber mounts?
Renovated Radios do carry what you need. As for the voltage, a wire should be at least 300V-rated.morzh — 11:13 PM
