I am looking at hiding a small PM speaker inside an old Crosley Musicone speaker. I have an output transformer from an old chassis where the output tube was a 50C5. I would think a 4 ohm speaker would work. My question is whether old transitor radios from the 60s had a similar speaker that might match up well with the output transformer?

:Brian, have several 60s, 70s transistor radios. Some play,some not. Could spare one

A discarded portable TV or just about any old AA5 radio could be your source. Even some obsolete CRT monitors have small speakers inside which can be useful. If you're not proud, prowl around on trash night for about half a gallon, and you'll be OK. Print a copy of this thread in case you are stopped.

Only problem is that a transistor radio speaker is very low wattage. (MW) Really need one at least 1 watt. Might try an old computer external speaker. I have some 3 inch round ones rated at 3 watts.
