I installed a new tonearm and audio cables and now have poor sound quality! Posted on: 23.11.2012 by Temple Handlin I recently replaced my tonearm, rca's and internally grounded...my sound quality is crappy now...and my soldering skills suck but everything is connected. Do you believe I should assume its bad soldering? Its not much of a hum or popping just poor quality while playing the music...any thoughts? PS: I used new car audio cables, do I need to remove the ends of the new cables and do something at that end too? Thanks all! Im working with Technics 1200 m3d | |

| Dannielle Dingey 24.11.2012 | I'll try to help.... First, crappy sound = ?? distorsion, low output but clean, only one side, ... If you have a multimeter, check the connection from RCA to tone-arm pins I presume it's the soldering, did you tin the tonearm wires before soldering ? Always use fresh solder on the pcb, remove the old one. Don't use to much solder, the Just try again and stay calm, test before you assembling the rubber base. To connect new RCA cables, you need to cut the male plugs on ONE side. Then you need to remove the rubber shielding to expose the coper grounding wire/mesh. This you connect to the side of the PCB connection The core of the RCA is the signal, that wire you connect to the center of the PCB connection. (see picture below) Good luck ! Ps. sorry for my bad English PSS. the correct connecion is this one: 1Undertonearmexposed.jpg Picture curtsy of Koptapad (clickable) |

| Federico Vilas 08.12.2012 | yeah, it takes a little practice...it's always easier to prep your wires first, again, I always twist the -R and ground cable together when internally grounding the deck... once all the old solder is off the board I put brand new solder on the board without connecting the wires...then, it's as easy as applying heat for a ms to connect the wires... you don't want to hold iron for too long b/c you could mess the board up with the solder getting too hot... you can look up pictures to show you how it should look |
| Dannielle Dingey 07.12.2012 | You internal grounding is connected correct, but the soldering is 'not so good' to stay polite Remove the old solder with solder wick and start again with fresh stuff. You did it right when the solder stays shiney after going solid again, test you solder on quality and try to use the best soldering iron/station you can find/buy/borough. Stay positive, notting so rewarding when things are finaly working like they should and you DIY But I still believe you first need to messure the current connection, to be shure you not fixing what ain't broken...and start looking elsewere. Good luck ! |
| Temple Handlin 29.11.2012 | So those photos are of my first attempt. I still have to buy the stuff to remove the solder, then I can make my next attempt...see how I did that "internal ground mod" I wonder if that's incorrect also? |

| Temple Handlin 26.11.2012 | Thanks for your responses! I havnt had the chance to open it back up but Im going to consider my issue being the solder. I only touched the iron to each point till it liquified enough for my wire to stick, no new solder etc. I believe im going to re-do my work but will clean all the old solder off the pcb then go ahead and resolder with fresh solder....what kind of solder are you using? Thanks again, really appreciate your advice!! Nick ps: Ill upload some photos shortly |
| Federico Vilas 25.11.2012 | yeah, got to use new solder and be patient... for some reason I always end up with 20/16 readings L/R for my outputs...fresh solder, new wires, new tonearm, one side is always slightly louder BUT sound is good |
