OK, I am working on this. We have a few more urgent projects, but (since I want it for myself!) I'll get to it pretty soon.

The idea is to convert the CF section of a Foreplay to a high-pass second order function, and add a FET-based lowpass for the low frequencies. This assumes the lows are going to have a big solid-state amp anyhow, so a solid state filter won't do that much harm. It would not do for a high crossover frequency, because you'd want a tube filter for the midrange. In a FP-III, the second set of output RCAs would allow dual outputs, but there is no easy way to put in level controls. It would rely on the (sub)woofer amp to have plenty of gain and its own level controls.

Hopefully it will fit on a small PC board mounted on standoffs from the tube socket. There are a couple of technical issues I want to sort out before saying any more.
