Hello, guys. I'm wondering is it the value of resistance R1 and R4 won't affect the output voltage of amplifier ? For original design, R1 and R4 resistance is 1K respectively. For 2nd design, i have changed their value to 500. After that, I have compared the output voltage between them. I found that there is no different between them. Why? Can anyone provide some opinions ? Thank you . Your help is greatly appreciate.
