Hi guys. Sorry about my last post and thankyou for your advice. MrAl has hit the nose on the head in his reply. I would like to see how it would be done. I found this circuit and I think this is the sort of thing I mean ...

Could you tell me if I could get this circuit to do what i want? I have all the components except the correct transistors It states 3x BC558 and the oly PNP transistors I have are BC327 Would they work? If not I will get some and have a go unless of course any of you could point me in the right direction.
Thanks again for your time
Jeremy
