I took mine apart, only the Speaker that contains the On/Off Volume— Potentiometer. That Speaker fell off my table and hit the floor landing on the Volume control knob, since then the Speakers do not work unless I insert something to keep pressure on the Volume Control’s shaft. Is it possible to obtain and replace the potentiometer/On/Off Switch…?
Yeah. Same here. I was blown away of the fact that there are no trasistors. Zero. None.
There is one IC chip, SC1863. But I cant find info on it.
Actually I just want to use it as a portable usb powered guitar amp. But I cant get my head around no transistors in it. Weird, huh?
