There would be a transition time I think.

This could be possible.

If they are dried out, then capacitance got lost. If the the oxide
coating is broken, they short.

What is a capacitor used for, that could cause delayed trouble, if it's
broken, instead of causing the trouble all the times?

IIUC you hear the crackling only, if there is an audio signal, there's
no crackling, without an audio signal.

This page indicates that the power supply caps.... well the whole power supply, is less than adequate already. Loosing capacitance will affect the sound at higher sound levels and not so much low levels or xero levels.

look at the 6th paragraph. I am not suggesting going to the lengths seen here as it is obvious much more money was already spent just buying 3 of the delta1010s and other equipment than you wish to spend.

I do remember (from my TV days in the early 80s) watching the monitor CRTs get a growing moving "blob" that started as a small bump at the top right of the screen and over a few months would grow to a blob that covered the top portion of the screen. It was always moving... this was fixed in all cases by replacing the PS cap. These were electrolytic caps they do wear out sort of gracefully.
