Here's a summary of the specs
Phono Section
frequency response falls within a 0.5 dB error band from 30 Hz to 20 kHz
-1 dB at 20 Hz, -20 dB at 5 Hz, to offer great suppression of woofer wobbling
33.4 dB of gain at 1 kHz
2nd harmonic more than 100 dB down with 20 mV RMS input
140 mV "overload" at 1 kHz produces 6.47 volts RMS out of the phono preamp
Line Section
Output clipping level typically greater than 8 volts into 100K load. Most amps only need 1 V RMS to drive to full output
Distortion at 1 V RMS out is only 2nd harmonic, and it is better than 96 dB below the output level
All 1% metal film resistors for accurate gain and matching
