SIGNAL/NOISE RATIO

AMP6 from 41hz.com TA2020 kit - stock configuration

S/N is generally good. We can see peaks for 60 Hz and harmonics, the disadvantage of having onboard power supply. Overall, very quiet.
0dB =7.5V RMS for 5066, Fenice, Super-T. 10V RMS for AMP6. Noise is combined amp and PSU noise. See notes.
