Maybe you can find good circuits here (and also help if you need):

I think one of the best thing about diyAudio is that you can come in, do a search, and find lots of projects like what you're asking for. However, you do have to search the forum to find the good ones. There are several designs that have been built by multiple members, so can be considered tested designs (at least to the point that people have successfully built them and are happy with the results). If you're looking for a phono preamp that uses 2SK170BL then search "phono preamp 2sk170" and you should find some candidates.
better than matched SK170 is ordinary unmathced JFE2140 (if you find something good for input)
