Default BABY MONITOR OVER VOLTAGE APPLIED

Not sure if anyone can help me here.

applied incorrect voltage to this circuit. i think around 9/10 volts were applied instead of the 4-5 indicated.

of course it stopped working. not sure if it can be fixed.

i've been testing at certain points to see what has blown.

1st transistor looks ok.

but the 1st processor/opamp? i'm not sure. it has 5 connections. only 2 are showing voltage (inputs?). the other 3 0volts.

any help would be apppreciated.

thxs.
