Default Re: Newb Stumped on a Derwent

Go in with a signal at the Volume control. Assuming the control has one end to earth. go to here and the other two pins in turn. One should vary with the control, the other shouldn't. Use music, anything. Does not matter. Make a lead with 0.1uF caps in it (one in series with earth, one in series with live) and use anything that comes to hand. An MP3 player is perfect.

Is there a type or a model number with this set? Then we can look for a manual for you.

Cheers,

Steve P.
