Hi Meghan and welcome,
As Mike said as long as they have the proper numbers your OK. You could do a very cursory test by using an ohm meter by measuring the resistance between the to fat pins on the base of each tube. What that will tell you is if the heater inside the tube is good. The heater is the part that glows when the set is on. If the heater is bad then the tube is likewise. So you should see several ohms between the two pins.
GL with your project!

When my pals were reading comic books
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.
Circa 1966
Now I think I've got!
