Bi-amping ADS L-1590 or L-1290


I have looked around everywhere trying to find out how to bi-amp the ADS L-1590's without having to use the impossible to find PA1 amps. Has anyone done this with an external crossover?

I have a pair of PA-1's that need some repair. Does anyone know any vintage repair shops that would have experience with the PA 1's? These puppies were hard to find I want to get them repaired correctly.
