Question Tube active low pass crossover

Hello Diy members,

I am looking for a schematic of a tube active crossover .
I am only going to use the Low pass output ,crossover frec. is 160Hz
Steve Bench has a nice design based on the 6dj8-ecc88
has anyone any experience with this design? Or has anyone built something similar?

All info is welcome.

I found the following schematic for a 50Hz lowpass tubed crossover (12dB/oct slope) somewhere on the internet a while back. I'm not certain, but I believe the frequency can be changed via the component values by back calculating using the formulae here.

Click the image to open in full size.

I've dug around the Marchand site some and looked at their manuals. From what I've seen, their tubed crossovers appear to be basically two of the same circuit chained together to create the 24dB LR slope.
