[QUOTE="Ingvar Ahlberg, post: 840327, member: 15447"] So, leaving the source for now, next round back here i plan to look into tweaks, simple waays to improve performance, round three is going to be about modifications and rebuilds. Moving on to where we put those RCA plugs and the ground wire mentioned by Shamil, and first step is to find the best point for that. With amp powered up, signal wire from TT connected and volume pot turned up to Your normal listening level or until hum is audible, TT running but no record playing, now we look for the best point to connect ground wire fromm TT, not allways the ground post on amp/preamp and if MC cart is used and a step up device is inserteted between TT and amp there are a lot of options. Try grounding point first, if hum dissappears all is well, if not quiet then try direct chassis connection to amp chassis/power am chassis, Step up device chassis, use connection point with lowest hum, please note that som set ups have the lowest hum with ground wire unconnected.
