Got an email from Craig today with pic's of the phono stage. He didn't say that this is the final final but I don't think he would've sent these unless it's release is eminent.
Here's some operational info;
The TA settled into two 12AX7, and one 6SN7 for the buffers.
It runs on 300V so input over load is a non issue.
48dB of gain moving magnet.
72dB moving coil set for 150 ohm loading.
Input transformers are Cinemag.
I am using .5% tolerance silver mica in oil caps for the critical midrange eq.
RIAA accuracy plus minus .25dB 20-20kHz.
MC loading is user set 37.5, or 150 ohms.
MM loading comes with 47K, 100pF but can be user set to anything via barrier strips.
The power is on a 5 pin XLR, and if one loses the umbilical standard lighting 5 pin cords are available.
