I breadboarded a circuit a while back based on Harry Lythall's (SM0VPO) website.(http://web.telia.com/~u85920178/use/stereo.htm).
As I remember, it worked ok, but signals on the edge of the filter skirts produced annoying sounds. I was going to put it in my HW-8. It is now on the "gotta get to that" shelf. 
As I am almost finished with my K1-4 (2 transformer windings + alignment), I might play withit again. The concept seems solid with the proper tweaking. Perhaps if I replace the opamps with 12AX7s ;). (Sorry- couldn't help myself!)
Hope this helps-
