RE: Capacitor cooker / Break in?

Sure. A tuner or a CD player set on REPEAT will do the same as a cable cooker.
In real life, I am an MD/scientist, so I can periodically "borrow" a DC power supply from my own lab at work. (We have a couple of obsoleted ones that just take up shelf space.) However, Lambda DC power supplies are easy to find on eBay. (Lambda is a reputable brand. BioRad is one other.)

Now where does that pesky load resistor go, in series or in parallel? You just want to be sure that the DC PS or the white noise generator does not see zero or very low impedance at any frequency from hot to ground. The impedance of a cap to DC is infinite, if the cap is not broken. The impedance of a cap to AC is linearly and inversely proportional to frequency, i.e., high Z at low frequency, low Z at high frequencies. If you put R in series with C, the Z cannot ever go below that of the value of R. So I tend to favor the series connection.
