Replacement Capacitor Question

[AndrewT]

Here comes dumb questions.

What will that do for me?

What should I use to do the measurement?

How should I do the measurement?

The measurement will tell you if the noise/hum is in the amplifier or in the connection/source.

Use a DMM set to 199.9mVac to measure the output noise/hum when the input is shorted. Don't use your ears to measure.

Thanks.
This is what I have thought for a long time. But not until I see the discussion does it occur to ask for confirmation.

Its one of those things that's not very easy visualise.
