I have a NAD receiver and want to switch out the old NJM2043 op amp with a newer model but the catch is it's getting + & - 17.5vdc and that's a bit close to the max of most modern ones. I want to drop the voltage down to around + & - 15vdc.
My question for someone more knowledgeable is, it has 24vdc going in and 17.5vdc coming out, does this work like a voltage regulator and can I adjust the value of the 3.3k resistors R629 / R631 up or down to get the desired voltage? If not what do I have to change to lower the output voltage?
