Hello,
If you want to have a good read-up as @WHONOES said on opamps, have a look at the PDF I posted in post #545.
( https://www.mouser.com/pdfDocs/analogengineer’scircuitcookbookopamps.pdf )
An other PDF will be "opamps for everyone":

Did a little test today, i connected an audio input to the phono jack at the rear of the amp, then connected a speaker to the 0v and In--R, at connection 9, i did this for both chanels and i do get clear audio and the volume/gain on the front panel seems to work correctly, so i think the pre amp is working ok

Yes i do, the more help the better, however i am waiting on @WHONOES to get this ossiloscope up and running, there is nothing more i can do apart from take readings, different people work in different ways, i am just trying to gather as much knowledge as i can, hope this isnt an issue

Well, hopefully i will receive some goddies from @WHONOES soon and i will be able to use my virtual scope and sig gen to see whats happening here, massive thanks to him and everyone else for all your support, i have no idea why the penny hasnt dropped yet, but hopefully it will soon, i hate looking stupid!, If i were to blow my own trumpet i would say find a better motorcycle mechanic in the north of england, you would find my garage always croped up, (cleveland county scooters )

Hello,
How are you going to fix the PCB in the box?
You might want to use some stand-offs:

Hi, i have fitted the IC,s with the top to the cut out in the sockets, as in pin 1 top left, as for fitting everything into the box, i will first work out best positions and then look at insulating the board from the case , also @WHONOES , is there any issues if i remove the LED,s from the board and mount them remotely so i can have them visible through holes in the aluminium box ?
