Good News From Head-direct     Dear XXX, Yes, the imbalanced problem has been solved and the one selling on ebay is same as the one in China. - head-director

I want to buy one recently. Has the imbalanced problem been solved? What I found on China BBS said one year ago, 'the chinese version of EF2A changes to the ALPS Potentiometer, which slove the imbalanced problem of sound channe.'   Or whether I could replace it by myself?
