The short answer is probably yes... easily, probably no. If you are lucky and only have one or two shorted transistors, then you can cut the leads on those and see if it powers up without blowing a fuse. Also check for shorted diodes and burnt resistors. If all FETs (or most of) the FETs mounted to the heat sink are shorted then it is probably not worth taking the chance putting the time and money into fixing it, just to have it smoke again. Also they are likely in parallel so it is a little more difficult to determine the bad one as they may not all be bad. Measure with an ohmmeter and find the one with the lowest resistance and remove that first and keep going until you believe you have gotten them all. Normally repairs like this are not for someone with little or no experience on amp repair, but if you feel like taking it on, good luck!
