@Hasnat: I also came here while looking for two replacement for my Cambridge and creative speaker. How you fixed +/- on AC to AC supply? have you converted to DC? And the sad thing is, As I have tried many transformer from local market.. all of them even failed to ensure 12v. Amp . is far away. NB: have u tried to collect something like that from mohammadpur; jeneva camp trash market? Answered by mahmudulme, 12-Dec-2017 16:09 PM
