Buzzing from speakers on TT rig
Looking for a little help or suggestions:
I have a Marantz TT15S1 hooked up to one of several amps. There was 0 noise in the beginning. I was using the Phono Input on the MF integrated. I added a Rogue Triton phono stage and all was good for a few days. Then the buzzing started. It was to the point where if you touch any point of the tone arm it makes weird static noises and touching the ground wire into the Rogue makes loud pops! I re-arranged the wiring and it seemed to help. Now I moved everything around on the racks and it's louder than ever. I took the Rogue out of the circuit and ran through the phono on the MF A1008 and there is still a slight buzz but not a violent snapping like with the Rogue. Ohh and I floated the ground on the Rogue and it made no difference.
Even through using only the MF phono input I can make the buzzing vary a little by wiggling the ground cable around. Very frustrated. Is there a better way to ground that may help, could it be in the cartridge or TT wiring? My digital system is 100% noise free so I think my power is ok. Rogue is being shipped back for a replacement but I hope I don't have the same thing when I receive it. Should a vinyl rig be basically noise free or should expect some static? Sorry for the long winded rambling post! I am very new to the vinyl world.
Thanks in advance for any ideas!

@mofojo This means whatever is wrong was moved with the rest of the equipment. I've serviced 1000s of turntables and preamps; the most likely thing here is as I suggested earlier- a bad connection- broken wire. They can be broken inside while looking perfectly normal. |
Thanks Ralph. On the Marantz unit the rcas and ground that would normally be be replaceable at the back of the unit go all the way to the phono pre through the tone arm into the cartridge. I’m looking this up and not coming up with anything for a replacement if needed. I’m calling it tt15s1 wire set and tt15s1 cartridge wiring? Something else I should be calling it? Guessing I need to try and call Marantz. I’m going to disconnect and reconnect the 4 cartrdige wires and re seat nice and tight. If that does not do it I guess try and order a new “wire set”? Seems really strange something in the wiring would go bad or break when the unit is just sitting there. |
@mofojo Again, try a putting a wire from the base of the arm to the phono preamp ground and see if that fixes it. If it does then you would simply make that connection more permanent. I've been doing troubleshooting since the 1970s; one rule of troubleshooting is its not worth it to speculate why something has failed when you know it did. Just fix it and move on :) |
