Selling my Dennis Colin Phono Preamp Kit

This is Colin's Groove Master design: JFET input and ultra-low distortion AD797 op amps. Excellent full-sptectrum noise figure, headroom and RIAA precision. Kit consists of partial kit: 2 manuals (user and assembly), parts list, JFETS and circuit board. I'll include 14 .05% resistors that I bought for 7 important locations (in each channel).
Anyone interested?
Thanks - found it.
Circular PCB, 2 JFETS, box of 14ea .05% resistors I bought separately, portion of Collins' schematic.
