Are there any parts available for the B & W 801 series 2?

I friend of mine passed away and his wife asked me to sell his audio system. He has a pair of the 801 series 2.  All the drivers are good but one of the crossovers is fried. Does anyone work on these?? I don’t think any parts are Available. 
Looking forward Advice

"... That’s what his wife told me...."

I would verify that the drivers work. I have my doubts. 
Thanks for the advice. I ended up selling them to someone who showed up at the house for $350
