Evenin all. Got a problem with my Bug pro- in all metal I have a really unstable threshold. Anything over a gain of about 10 and the thing goes nuts, falsing like a bastard. Ground phase numbers ( the big central number ) are all over the show. If you touch the coil connection where it plugs into the control box it overloads. Disconnect the coil lead from the box and things improve slightly but the threshold is still really unstable.
In disc its not as bad but again the numbers bounce.
Any suggestions? Or anyone wanna buy it?
