The amp is going straight into protect. All fets and rectifiers removed. Also This amp uses an ir2113 chip. Would an ir2110s work as a substitute?
If you try the 2110 and you find that there is some odd problem and you can't find the cause, order the original. This happened to me in an amp. I don't know which way I went 2110-2113 or vice versa but I know that the original IC worked better.
