the K&K is a nice unit, no doubt. Lundahl iron is hard to beat in that application, esp. since it is amorphous core.
A friend and I are working on an all-DHT, transformer-coupled (mostly) phonostage project, using John's S&B stepups and RIAA. It will hopefully come together this fall/winter, we'll see. If it works out well, it would likely be a public domain project, probably.
the TX-102s could be incorporated for level control too, if desired.
I just got a new (active) preamp that uses tx-102 silvers and the Seiden switch as the volume control, it is quite sublime, the best pre I have ever heard or owned. Will post pics sometime. (Many thanks to John for those parts, of course)
