MPP Coil And Preamp Speed

[waltr]

Hi All,

I have scop'ed the preamp in (pin 2, yellow) to output (pin 1 blue) and notice quite a bit of distortion in the signal, especially overshoot (this is with NE5532)
See attached image ... will a faster opamp fix this?

I'm not sure what you think is wrong, or what you mean by distortion. A little bit of overshoot usually indicates slight underdamping and that's where you want to be.

I agree with Carl.
Also it is very hard to compare pre-amp output to input due to the Gain of 500+ to 1000.

The slight bump on the output is only a few mV which means it is only a few uV at the input which can not be seen on the scope.
