Alon Model 1 8" woofers blown

So, almost 4 years later I have another question. My Alons are 25 years old and I now run them with an integrated tube amp and a tube phono preamp.....I'm curious as to whether having the crossovers rebuilt or would the materials Carl used still be strong after 25 years? 

I blew the tweeters and Madison sound hooked me up with a pair that I think took the alons yo a new level. 

Parts can make a difference for better and for worse.  You can easily change the resistors to mills and upgrade the caps yourself for starters and you can undo the same if you do not like them.

Is there a company or technician that will rebuild my Alon 1 crossovers if I send them out?
