100v output step down transformer

Lots of people incorrectly thought that Japan and USA both use 110v as their utility power voltage, that's ----- totally wrong.
In fact Japan is using 100v and USA/Canada are using 120v utility power voltage.
Use a low quality 110v output will cause Japanese amps to work at 10% overvoltage and USA/Canada gears to be undervoltage.
Overvoltage or undervoltage both cause amps not working on their optimized bias and make them sounds worse than they should be.
Overvoltage can also cause amps overheat and shorting the life of the electrolytic caps.
Tube or Valve amps are sensitive the power voltage and the 10% difference in power voltage will cause 20%-30% reduce the life of the cathodes, since they are not heated to the correct working temperature.
The solution to the problems is, use 100v output transformers for Japanese gears and, use 120v output transformers for USA/Japanese gears.
For the reasons I mentioned above, I never sell transformers that output 110v.
I only sell quality transformers that output 100v for Japanese audio gears or 120v output for USA/Canada gears.
