Drill a bunch of holes and file the edges square. There’s no elegant way without a mill or the proper punch.
Another method is to drill a hole in each corner then use a coping saw to cut between them. Some filing will be nescessary to finish.
I drill four holes on corners and use mini dremel with flexible shaft to cut the rest between corners. Leave some space to the required size and finish with the flat file. Aluminium is easy to work with.
One might also drill many holes one next to the other and finish with flat file. Tedious, manual work, but the final result is the same.
It looks like it will work the pin spacing looks a little spread out on my data sheet as the only difference.
Can someone please explain why there are a million different optocoupler models.
It's been doing my head in.
Consulting the datasheets hasn't really helped me.

probably same reason as why are there so many "different" transistors around
was puzzled with same issue eons ago , just abandoned thinking about it

Wrong instruments!

My amplifier is always noisy.
Without anything in play, and increasing the volume the noise increases as if there was an interference, What can I check before throwing everything?😕😕😕

If increasing the volume increases the noise wouldn't that indicate the problem is up stream of the amp?
If you disconnect source/cd player is it still noisy?

Please post well-lit, in-focus photos of your project.
What opamp are you using, and what output Mosfet?

If you have 18V between positive and 0V and negative and 0V, then it is most likely some sought of wiring issue.
Did you follow Wayne's earlier suggestion on how to wire up it up using capacitor etc?
Edit: I can't remember if the amp is using 18V regulators, so my first comment relies totally on that being correct.
