Yamaha DTXpress/DTXplorer/DTXtreme

I don't know if this is the right place to ask, but does anyone have a copy of the yamaha dtxpress 3 drum module, there is a transistor inside that seems to have overheated and cracked apart, and I would like to know what part it is to order a replacement, and solder it back in.

Thanks for any answers
