Filter Capacitor Values-- Is it worth tweaking values?

[eschertron]

With the limited screen real estate and the sometimes awkward display options, I've used my phone only via the built-in mic. Close enough to accurate for me. Besides, aren't phones supposed to be wireless?

edit: but seriously, probably good enough to get evidence that low ripple harmonics are present.

Wow do I wish I could afford a spectrum analyzer

What I mean is less hum (120hz) overall, I’ve noticed that the higher the filter value, the more compressed, almost squashed the tone of the amp becomes.

I noticed something similar in vintage PP tube amps, but prefer to describe the effect of higher cap values as less attack responsive. My explanation is the influence of the filter on the time constant of the sag induced screen compression.

So my answer to the original question is YES.

To ensure reproducibility of results the actual cap values should be measured with a good LCR meter.
