If you talk with Rogue they might be ok with sending you a schematic, I don't know their policy but it doesn't hurt to ask. This would give you the option of using a good local electronics shop. If you are interested in a little tinkering sometimes when you pop the cover the problem is obvious (e.g. overheated & blackened resistor).
