Even smaller amps tend to use at least three, arrayed side-by-side in stages to filter the supply at points where the DC is passed along to the output transformer, the output tubes, and the preamp tubes, respectively. Larger amps might have twice as many filter caps, or more. In the case of individual filter caps, size does matter.
