Hi all,
Attached is a schematic of an audio op amp preamp I wish to build. http://www.rason.org/Projects/opamps/opamps.htm I will use a NJM2068 opamp enstead of the TL082. I don't have the exact capacitors that the schematic shows. Would there be a significant impact in the circuit performance if I substituted the caps with values say 10x higher (1uF in place of 0.1uF or 100uF in place of 10uF)?
Also this schematic shows adjustable gain by using a resistor on the output. Would it not be more desirable to put the adjustable gain on the feedback resistor?
Thanks
