B&W 801 crossovers


I am debating buying tube crossovers. I have a pair of B#W 801 speakers and was wondering what type of crossover or just have the speaker crossovers rebuilt. If rebuilt who?

I just had my 802 series 80 crossovers redone by Walt D'Ascenzo of Baltimore. He was a friend of Walter Jung and solved a serious electronics
issue for Wilson audio which they've continued to use. My 802's are better than off the factory floor. Walt has replaced the electrolytic caps, yes, but with mil. spec. parts  with results that are genius. He also turned my EAR 834P into something exquisite. His prices will be less than half of Northcreek and you won't believe your ears.
I know this is an older thread, but I have a pair of B&W 801 and 802 series 80 and am interested in upgrading the crossovers.  How do I get a hold of  Walt D'Ascenzo of Baltimore?  Does he have a website?  Any assistance would be appreciated.
BTW, Walt had revamped 801 crossovers for another customer with great success prior to the crossovers in my pair of 802 Series 80 , which will be buried with me.
