Speaker question

Hello everyone.
I purchased a 1948 Telechrom clock radio I would like to restore, but someone removed the speaker. Can I put a purchased new speaker in and use it as a replacement, or am I asking for trouble? The old output transformer is still there, the speaker was just removed.

Yes, you should be able to put a replacement speaker in the radio and it should be fine. Just make sure it's the same size as the original.

Thanks. I ordered a couple off of Amazon that I think I can make work.

Most of those speakers without the electromagnet are around 8 ohms if I remember. The usual things I look at on replacing a speaker is the ohms is first, next is the size/shape similar to original. Last is can I figure a way to mount it, make a bracket if necessary. I buy all the used speakers I can find. I bought a big box of speakers at a meet then used one of the speakers in a RCA radio with two speakers I bought at the same meet.
