hello TB'ers, so, i will be taking an Ampeg SVT II (non pro) to Argentina. The amp currently is set for US voltage and i'd like to know what is the best way to use is Argentina (220 Volts, 50 Hz). I can always use a transformer but these things are a huge, noisy and HEAVY. If you are moving this amp with a 4x10 the last thing you want is more weight to carry... I've heard that you can easily swap the voltage in the modern svt's. Not sure on this one... Anyone has any experience with an AMPEG SVT II? the serial number tells me is a 1991 model. thanks in advance!
