Hello!
I must thank you all at whis forum. I really enjoy reading must of the stuff her. Well after reading about the GainClone I decided to build one of my own and so have I done now.
I have only used 5 components. A 220k resistor from pin 8 to pin 3 and another at 10k from pin 3 to a 4,7 uF cap that is connected to the volym pot and of course a LM3805.
Everything works great, but if I disconnect the input and start turning upp the volume the GC starts to hum a litle bit, is this normal or is it some kind of disturbence or osiolation?
If this is normal, then there is no point in trying to get rid of it, but if this isn't normal then I have a little chalange ahead.

So what are you disconnect it for? You usually have some source connected to the amp,so if there is no hum when the source is connected why bother?
My gain clone is dead quiet on 95db speakers,even when I put my ear into the speaker,but I always care about proper earthing and grounding.
