Hello im from Brazil and my outlet voltage is 127v. Do all exportation 2203x models heve the same mains selector options - 110v, 220v and 230v? What the difference between JCM export models 2203-01-u 2203-01b and 2203-01e?
The difference between the -U,-B-E are the voltages for the different countries and the labelling for approval in the particular country. The electronics are the same in all the amplifiers.
