A friend and I are working on a DIY phono stage project that will be all DHT tubes (probably 3 gain stages total), and will utilize S&B TX-103 stepups as input trannies, and also the S&B 10k RIAA unit (once I get those from John... :) We should have it at least prototyped by this fall. It will have an optional S&B TX-102 in there too, so it could be used as a stand alone piece (e.g. control gain via the TX102). I may get Josh S. to build some chassis for it when we get that far... should be a good one! The all-DHT part of the project is the tough challenge, but should pay off nicely as far as sonics if all goes well.
Of course this is totally separate from the NOH and whatnot, but interesting perhaps since it uses the S&B Iron that John has worked so hard on as far as development and sourcing. ;-)
