If you have used CA3401 instead of a lm3900, and it's seeing 30V it will go

looking over the board briefly, i still need to do a lot more
troubleshooting but what i wanted to ask about was this,
anywhere so i put the old ones back in and system powered back on fine so i
switched them out with brand new ones i had and it cooked them within
seconds of powering up.
appears to be a short and the others seem to have no effect ?
