This purely analog tube phono stage has been re-designed using a more robust power supply and higher end parts throughout the signal stages. It is designed specifically for MM cartridges (or can be used with MC using SUT'). This robust phono preamplifier is completely hand built, and point-to-point wired- no digital circuitry or PCB's. It uses (2) 12AX7's for the first gain stages and RIAA correction, and a single 12AT7 for a low impedance output (600 ohms). This unit can easily drive an integrated amplifier or make a perfect addition to a preamplifier lacking a phono input.
