The ParrAmp Moving-Magnet Phono-Stage is a minimalistic circuit designed around the ubiquitous 12AX7/ECC83 miniature double triode. Although the gain of the stage is not as high as those using more tubes, the simplicity of its design results in an extremely transparent amplification tightly following the RIAA curve with a tolerance of less than 0.2dB from 10 to 30 kHz. The single tube design also makes it a highly delightful choice for tube-rollers. A version using the legendary 6SL7 tube is available under request. The lower gain of the octal tube may imply the need of a line preamp to drive less sensitive amplifiers.
