THANK YOU!!

If anyone can find something that will work on taobao.com please send me the link! i have went to 4 stores.. can't find anything and chinese websites i am just lost

So the ac/dc power supply already has a rectifier that is changing ac to dc. so when it goes to the amp it is going into a 2nd rectifier and will have a lose. i understand the rectifier and why it would have a lose.  I am not as familiar with voltage regulators and how they work.

I am not sure if this is the right place to post this! so sorry I am currently in china and i need a charger for my O2. I was looking around online for the wau16-400 but its a pain for me to try to set up an account and try to order something online because i dont have a chinese bank account. ...

I would let some one do it if they wouldn't charge me. i think i can make it fit and keep the batteries if i put the 1/4 coming out the back.. i know this is off topic from what i posted. but i know i can get a 3db bass boost gain with out a problem. I know i can change up the resistors and...

and.. bass boost..

all i want is the 1/4 jack. seems like its really going to be a pain. 

Do you think i could get the 1/4 jack to fit in the B2-080 case? 

I am wanting to build an O2. I found the parts list so i think i can find everything i need. other than building it with the 3.5 jack i wanted to build it with a 1/4 jack.  Have any of you done this before? If so do you have a part number for what i would need? and did you need a different...
