I produce an amplifier more than 40 years, and it meets a Japanese safety standard.
However, we cannot easily export amplifiers because an electric safety standard is in each country.
It is difficult for us to get the electric safety standard (CE mark etc) of each country in Japan.
Therefore, we encourage each wholesaler to voluntarily obtain the electric safety standard (CE mark etc).
