NAC 152 clone

[Jempie]

I have bought an NAC 152 clone, on the schematic there is and resistor R14
as feedback line of 12K

what happen is i change this

Looks like you'll change the gain?

This is a simple non-inverting amplifier. The voltage gain can be approximated to this formula: Av = 1 + (R14/R9). With the values given the gain is 13 (or 22 dB).

Changing the value of R14 alters the voltage gain. Be aware that the amplifier may become unstable if you lower the gain.
