I saw where someone has replaced the preamp in an HK unit and I thought was an interesting idea for an upgrade for some of my 2200 series stuff. I really like the tunability of the preamp. Even if no, I might do it just because i can right now with the 2245 still open on the bench. I know.. it's taking a long while but I had to rebuild a KX-1030 to replace my Fisher Studio that gave up so that jumped the line
I wont contaminate this forum with my Kenwood stuff but if you poke around over there, you can see the pics
