Thank you for your repsonse Grumpy Mike, I have some questions:
You need 0.1uF caps across the supplies
So anywhere there is a positive connection place a decoupling capacitor.
across the vertuial ground resistors
What is the vertuial ground?
Also put a large cap about 47uF as well.
Where should I place this large capacitor?
BTW: Your website: http://www.thebox.myzen.co.uk/Workshop/Introduction.html is VERY cool!
