Hello all!! My buddy (he plays g*****r) recently got (for free) a little Marshall 30w combo that has been fried. Apparently the guy that had it before wanted a little more power, so he took another a line out from another amp and stuck it into this Marshall combo and successfully fried it. I'm actually sort of glad I've found out about this, since this idea has occurred to me once... or twice....it wasn't a serious idea tho... really!! but then, I got G.A.S. which got rid of that idea Yeah, so according to my friend (I haven't seen the amp yet), the amp still turns on, but has this horrid sound and doesn't work at all other than that sound. He said that he's checked out the insides and from a visual inspection, all the resistors are burned out (prob more too, but that's all he described to me). So, we're wondering if we can just replace all the resistors and capacitors (if they're burned out too) and have a working amp. And, if that is possible, can we mess around with the resistance and capacitance of the stuff we put into it, and get a wattage increase (just for fun). Anyway, I realize this is somewhat vague, but any help would be awesome. Feel free to ask questions about the amp and I'll ask my buddy to take a closer look at some component of it or what. Thanks!!!
