Super MM Phono

Redesigned from the ground up! Now featuring an over-built outboard tube rectified and regulated power supply. Many updates to the circuit and componentry throughout to punch well above its weight class!

Pulling out the stops on this design, I now use an outboard power supply to isolate all power supply noise from the signal path. This, coupled with a toroidal transformer for the B+, dual chokes, lifetime-rated film capacitors, and tube regulation, ensures robust power filtering and delivery! A heavy gauge pure OFC 3-foot umbilical cable connects to the signal chassis. (2) low-noise 12AX7s with shields perform the RIAA amplification duty, and the output is delivered via a low-impedance cathode follower. All of this adds up to the phono stage performing at an entirely different level than before. Lower noise, increased dynamics, and plenty of micro detail delivered with the smoothness you would expect from a top-notch phono stage!
