How to convert a 117 volt amplifier to 240 volt Mesa Boogie Electra Dyne Amplifier using a TAD tube amp doctor power transformer.
117v to 240v Conversion of the ElectraDyne from Mesa Boogie
One thing that can be really annoying is the fact that many amplifier manufacturers no longer provide a power transformer that works on varying input voltages like 110/117 volts or 220/230/240 volts. Indeed it's almost as if they don't want us to buy an amplifer from them then tour around Europe or the USA or indeed anywhere else that the voltage is different than the originally specified amp.
Of course that really is a ridiculous situation. These manufacturers (and Mesa Boogie are far from alone in this) happily say these amps are great for touring the world, then in the next breath stop us by limiting the amplifier to its domestic supply! For real musicians (and not just for your bedroom like me and you) it is a pain carrying around that transformer and for step up units those can be very expensive. OK lets cut the bull... even in a bedroom situation those transformers are a real pain.
What's the answer? You have to be a little savvy on using a soldering iron, know something about voltages that will kill you and then get a power transformer (and in the case of this Electra Dyne) and sometimes a secondary trsnsformer, a couple of bits and convert the amp to the voltage you need. The good news is, that once you have done this the amp usually supports multi voltageuse so you will never have to go through it all again.
DO NOT ATTEMPT THIS CONVERSION IF YOU ARE NOT TRAINED TO DO SO IN ELECTRONICS AS THESE VOLTAGES CAN KILL YOU!
