Battery Powered Theremin

Hello,
I have an etherwave standard theremin and want to play it on streets. I found a battery powered amp but i'm not sure about connecting theremin to a battery pack. The power supply socket has alot of pin and i'm not sure to cut the cable to connect to a battery. If you know how to connect the ew standart to a battery please help me.
Thank you and sorry for my english.

Hi Paydayin, welcome to Theremin World.

The best approach - as recommended by some TW members who busk regularly - is to use a 12V Leisure Battery (or a deep cycle battery or a jump-start battery - basically any lead-acid battery with a carrying handle!) and a small Inverter to give yourself a portable and rechargeable mains supply that will power your theremin and your amp etc. for several hours.


(Perhaps Cihan Gulbudak can help. He is a thereminist (his stage name is Meczûp) who lives in Istanbul and has done some busking with an etherwave. You can find him on Facebook, MySpace and youTube: http://youtu.be/On6byUJlTe4.)

Thank you very much for your answer.
