Audio Systems: speakers, cerwin vega, antique electronics

Question
Hi, I have old speakers from 1976.The name is Cerwin Vega.The model is TR 12.The problem is there are no fuses or fuse caps.so the speakers do not work.Radio shack, Cerwin-vega,Part ewpress do not have them.Do you know where I maybe able to get these for sure>

Answer
Believe it or not, I had the same speakers back in the day. Let me see what I can find out and get back to you.
I see what you are running into. I'm finding the speakers all over the place, but these specific parts are tough to find. I thought for sure Antique Electronics Supply would have it, but no. I'm gonna keep at it.
