VR1 in the signal rectifier will be used to change the gain rather than the meter circuit. R3 and R4 should use the values shown in Figure 1 for best accuracy. Figure 4 - Simple Full Wave Rectifier and Preamp. The signal rectifier needs a supply of ±15 volts, and the audio signal is fed directly into the 'Audio' input of the meter circuit.
