I am lately Experimenting with some electronics made for internal Japanese market and naturally it is 100 volts. Some of the electronics which runs 100 words is a ok to work within USA voltage of 120 Volts And some not. Typically, we use converter transformers volts and I wonder if the people who involved in this detected any issues.  I have two converter Transformers and they sound different, and the electronic run through those Transformers sound different between 100 and 120 volts.  So, what is the best approach. Should I change a primary transformer for my electronic components in order not to have a proxy transformer? should I burn 20V by some means? There are many other options. so, who have experimented with this? "I wish I could score everything for horns." - Richard Wagner.
