Had to step away from this for a while, doing my head in. Still high pitched whirring noise but also getting some signal through, will audio probe again when i have time. component values checked again and ok. everything has been reflowed. did have it working outside of box but everytime i put in enclosure the noise comes back and stays. IC values taken below, dont think i have posted those yet.
IC 1 1-8
5.1V, 5.1V, 4.9V, -3.9V, 5.1V, 5.1V, 10.4V
IC 2
5.1V, 5.1V, 5.1V, --4.4V, 5.6V 5.6V, 11.3V
IC 3
5.6V, 5.6V, 5.6V, -4.4V, 5.6V, 5.6V, 5.6V, 11.3V
ic 4
5.6V, 5.6V, 5.6V, -4.4V, 5.6V, 5.6V, 5.6V, 11.3V
IC 5
5.6V, 5.6V, 5.6V, -4.4V, 5.6V, 5.6V, 5.6V, 11.3V
IC 100
7.7V, 3.7V, 0, -2.6V, -5V, 2.9V, 4.5V, 7.7V
Don't know how normal the charge pump values are but the rest of the IC's seem normal right??
