Hi,
This should be the first time I will be using a SW to test a RIAA preamp response.
I was thinking of copying the settings I use for testing power amps, but I am not sure it's correct.
They are: PULSE(-.4 .4 0 10n 10n 25u 50u 10)
Would they be fine for this new test?
I would use an AC analysis. Produces a nice plot of frequency response that you can compare to the RIAA curve. That is what I did when I looked at the Carver C1 preamp stage.
