Build & measurement pics Low MC pre-pre
1st pic right channel
2nd pic 1kHz direct audio generator 30dB attenuation
3rd pic lefht channel
probe x1
4th pic Low MC pre-pre including capacitance multiplier
5th pic R-Core separate PSU
Are the measurements OK?

Voltage gain in dB = 20 log Vout/Vin
Now I only need to know how calculate the volts with the scope, help please?
You need see 10X the input but don't feed it 100mV, feed it 1mV. If you don't have the means try it on the actual TT.
