    We often get comments on amps tone and volume characteristics from all over the world. But, different countries use different mains power supplies, that is, different voltages and frequencies i.e 110v 50hz or 240v 60hz. My question is: would an amp marketed under one brand and model name but designed to use the USA power supply have the same tonal and volume characteristics as the same make and model designed to use the UK, or Aus, or European power supplies?

    Provided the B+ and bias voltages end up being the same, and the d.c. filtering is the same, they should perform the same.

    I know they should, but do they? Has anyone ever carried out any experiments using transformers or generated power supplies to get a definitive answer?
