Vertically stacked capacitors

I usually prefer to remove any additional input filter components only after I have solved whatever problem I had been going after. In the case of the vertically stacked capacitors, for example, I would then start removing each additional capacitor one by one (with the help of two soldering irons applied simultaneously to both sides of the stack), confirming, at each step, that the problem had not come back, and that there was not a new one now ...
