Modern amps now on the market are now not as much of a problem.
Multi-tapped transformers and step-start circuits are incorporated in
most designs.

It is the old pre-1980 amps that need the attention. Most had no glitch
protection, step-start, and only one "tap" on the transformer(s). They
assumed that everyone had 115 or 230 volt mains. Most of the reports
I have seen (including my own) indicate that 125/250 volt mains are
becoming the norm in this country. To exasperate this problem, too
many folks try to push these relics to 1500 watts + output when the
components and cooling were chosen for much less. The cumulative
effect will take its toll, sooner or later.
