I do not have this equipment but I only have this service manual. The manual is useful as a analogy active crossover using Buffer stages. I have attached the circuit diagram of this crossover here and you can use the NP B1 buffer to replace the transistor buffer and then you will get a good B1 active crossover.
I have not tried B1 active crossover using this design yet as I do not need a crossover at this moment.
There is a diyaudio discussion about B1 active crossover @diyaudio.
