I recently recieved my PowerBook 145B after days of waiting and its great! I love it, and its so fun to use. But the only issue with it is that the speaker is broken, as I dont get output. I can hear all the normal sounds like the chime and alert noises when I plug in headphones, so there is no issue with the board, just with the speaker. I cant find any replacement speakers that are genuine and I dont want to get another one for parts. I have an idea, to replace the speaker with a small laptop speaker, that of 8Ω, which costs nothing to buy. What should I do, should I try a small small 8Ω laptop speaker, or should I try to hunt down a genuine one, on where I dont know where to find one?

Many thanks!
