Ground Scheme mojo 18 watt TMB001.pdf
I'm a new member on this forum. I am building a mojotone 18 watt TMB kit and didn't like the grounding scheme. A ground buss on the back of the pots and no direct chassis ground for the inputs. I read the posts on this forum regarding grounding and made a sketch to make some changes. See my attachment. I have a couple of questions. 1) I want to add a chassis ground for the high gain input which is located near the center of the chassis. Should I add the chassis ground close to the high gain input to keep the lead as short as possible or should I move it as far away from the PT as possible? 2) I want to add a ground wire attached to the terminals as needed between the pots and eliminate the ground buss attached to the back of all pots. Does it matter where I attach the ground wire to the ground buss on the board as long as I keep it in the preamp section. Mark
