why not consider an active tube xover


to go with those tweaked paramours? Schematics are not hard to find, heath kit had one, "marchandelec.com" sells a current kit that is tube based. Wayne's suggestion involving the 47kohm loads might be hard to implement unless you know the input Z of your amps is still 47k. Does the z vary when your attentuator is stepped? I don't know either.
Your current crossover parts can't be used, they separate the signals when working into 8 ohm loads. There is a reference to "Biamping" in the FAQ section, I think. Doing it properly requires an "active crossover" that separates the sound from the preamp into LP and HP, to be fed to your amps. Sam
