Next two.

Last two.

OK, shame and I should have thought to mention about the capacitors being polarised but we can deal with that in a bit.

Handily the two 8 pin chips are connected to the 12V rail with a wire link each so we can lift one end of them to isolate the chips, I've circled them

BrianHG:
If it is not the caps, I can only see that IC6 is blown pin 5 to 8 as a short, but how?
This is so rare to near impossible with all the other IO connections to that op-amp having huge series resistors.
Being CMOS, the way it is hooked up, you would need an absurd jolt to make that happen.

I've lifted one end of each of the wires and the short remains.
