it's been difficult to actually finish these projects, some of them were started in November and just now getting finished due to all the Christmas rush orders, and then after New Years I guess people decided to buy whatever they didn't get for Christmas, and started ordering finished preamps, which can take me up to 3 weeks time squeezed in between a hundred emails a day and half a dozen orders that need to be filled.
So here's a review of the phono preamps I've got available.
The PH6 is the same one used as an upgrade for the PAS3, and is the same circuit used on the SP8 combination preamp.
The PH9 I just finished 2 weeks ago, and it works GREAT, it's sounds fantastic and has lower noise than I expected (I always EXPECT noise in a phono preamp). I only have one left until I can get more boards made which may take about 2 weeks. I haven't even posted prices on my website yet.
The PH11 is very similar to the Transcendence Phono pre that sells for $700 kit, my kit is $500 and has the advantage of a tube power supply which I consider a must on any tube preamp. I actually finished this preamp last November and it blew me away at how good it was, which is a good thing considering that the tubes alone for it cost $140 (a quad of 6C45pi plus a pair of 12AX7 and a 12X4 rectifier). It is DEAD SILENT and sounds fantastic.
The PH12 I'm still fine-tuning, I built some of these about 6 years ago and they worked fine, they use a pair of 6922 tubes (they CAN sound a little sterile and they are known to be microphonic) and a JFET as a current source, the combination theoritically should have about 10X less noise than most common phono preamps using 12AX7, I'm getting some hum on the one I built so I will be building another one and then trying various things to get it working at it's best. It also has the advantage of a much smaller footprint size inside the chassis.
