Default cmoy bb , jds board, self induced woes

I guess I have learned my lesson. When I built this amp I didn't clip the leads and now I have a serious issue. I don't see any leads shorting but when I touched up a solder joint for the power yesterday my amp quit working. Now the op amp, which is probably toast, gets REALLY hot to the touch when I turn it on. Can someone offer some suggestions on how to find the issue? I have a lead clipper on the way but in the interim it would be great to find the problem. I do have another set of op amps on the way.
Cheers

Eh, I rechecked all the solder points this morning. I am now getting audio but it is VERY weak. I looked at the TLE2426CLP I see approx .5 and .45 volts on each side. I suppose its toast. Who knows what caused it. I reckon I'll scrap this pcb and try to crib what I can and put it on perboard to see if I can recreate it.
