input connection and ground on ucd 180
I am in the process of putting together my first amp.
How should i connect power ground and signal ground? I planned on not connection power ground to chassis, is there any reason not to? I use unbalanced rca inputs. What/where should i connect neg input and ground on the ucd modules? Can i leave the ground pin on the ucd unconnected??? Should i keep the power ground (O volt) from the rectifers floating or do i need to connect it to chassis? I use a 2x33V trafo with no 0 Volt line and 2 bridge rectifiers. Advice needed. some pictures: |

Use double insulation transfo and parts and distances. Neg input and ground to the chassis. Floating PS, floating AC ground.

Alternative is to use the standard grounded box, but I don't have links to offer for that. Guy |
