I've done a few of these. I found that the internal ground method resulted in a hum on the speakers. (though it has been okay with other tables). For best results, the chassis ground should be kept away from the signal ground, to keep that current away from the signal.
@JosephAzarUAV8 жыл бұрын
First person to say this. It makes no sense to attach ground to shield of one side. Ever hear of ground loops? Sure you have, it is the HUM you often hear when attaching a table to inputs. There are cases where the ground must be lifted, or a ground wire applied in a differing spot. Doing this mod insures that you CANNOT lift or change grounding. Sending the table ground down one side can loop any stray current down that channel, through a preamp, out the AC neutral, and back to the TT via the table neutral, causing hum and noise. There are many other scenarios that could cause hum and noise via this method, too numerous to mention. In a static environment, it is much easier to make permanent changes. But traveling to differing venues where power, ground, neutral, heavy HVAC, ballasts, lighting equipment, nearby TV, radio and other RF transmitters, plus other RF (microwave ovens for instance) and electromagnetic spewing items are, this could be a disaster of a mod. All these items can spew interference through air and via house power system I am not saying it always will, but in my decades of TT setup and service, I have seen some very strange things that took creative analysis to cure. Connecting a ground wire is easy and quick. What really is the problem?
@DjMarky_G8 жыл бұрын
Your totally right, it can cause some weird issues if the ground is looping. It all depends on a person's setup also. Some equipment does require a ground toward a different area in the circuit. There are some other RCA wires out there that have poor shielding that can also cause ground loops. As you said there are multiple factors that can cause some problems but are rare. If I do find issues and a humming is present it can also be caused by a failure in another components ground circuit, or another issue that is preexistent in certain set ups. However I have yet to see this mod fail when done correctly. I have come across ground looping in one scenario when the club removed ground on a power plug to the mixer in order for it to fit the outlet. When my tables were attached a hum was present. The fix for this was just to add a RCA splitter and just ground the outside shell of the RCA plug. The reason for doing this mod is for several reasons. Djs often come across shotty equipment all the time when going into gigs. For example, missing ground screws or damage grounds on mixers, the chance that the ground wire was ripped or crush, serato or tractor not getting a clean signal from the attached ground. The circuit that the external ground attached into the RCA shield provides a clean signal 90% of the time. I have yet to see turntable failure from this mod though since in the technic 1200 the ground circuits are separated to an extent from the motor. It all depends on the set up. But you provided some good information for people!

Another factor to consider is how you will be using 1200. You'll notice there are 5 wires coming from tone arm - no common ground. When you do the mod you are injecting noise in to the signal. In a club - probably not noticeable. If you're using in your home for best playback potential - probably not a good idea. You could also get in to scenario where you have a ground loop and no longer have option of moving ground wire around. Solution might be to be to add external switch to change between internal and external ground (just a thought - not tested!).

Awesome, many thanks once again for the very invaluable info! I would say that taking into account the massive amount of use my decks used to get (I now use a Traktor S8) the constant time would be approximately 7200 hours and this is a conservative estimate. I went on the assumption that on average I was probably using them for about 14 hours/week and did this for at least 10 years and actually probably more when I think of it but it's a ballpark figure and well over the 3000 hours in the book.I agree with you on the not oiling part as they're still running smoothly and even the lights work too with their original bulbs. I was always very careful to keep a close eye on other people using them as you'd be amazed (or not!) how people can mistreat them without even knowing so e.g. by stopping the platter, fiddling with the weights etc. Anyway thank you for coming back on my post and wish you all the best!

@DjMarky_G8 жыл бұрын
I have only oiled my tables once. After that... I don't think I would need to oil them again until I have kids and give them my tables haha. With that said Technics does recommended after x amount of operating hours. I am not sure what viscosity rate the oil is but I have used "liquid bearings" oil (il provide you a Amazon link) I wouldn't recommend any other lubes due to the lack of information I have on the type of oil. (Last thing u want is oil all over the place) there are two ways to apply the oil. One way which is quick is just remove the platter, apply 2-4 drops directly onto the spindle, and wait a couple hours for it to drip down into the motor. This does pose a risk because if there is any build up (gunk or dust) the oil will just layer on top of that. The proper way (which I did) is to remove the platter, unscrew the top magnet (big black doughnut thing), unscrew the circuit, and without unplugging anything just lifting up and remove the spindle.
@DjMarky_G8 жыл бұрын
Wow didn't know there's a character limit on comments... Well now I know. Next step. Clean the spindle and apply 2-3 drops directly. Then reassembly. You aren't oiling the motor because it is a magnetic drive motor. The only thing you will be oiling is the spindle. But let's do the math. 3000 hours is 125 days of constant operation. Depending on your use, if you are playing on the same set for that many hours... Then you must be fucken amazing. But other than that. I would do it once every say... 10 years or so... But to be completely honest... I wouldn't bother. I mean the turntable isn't being played in a middle of a desert, or exposed to the elements... Unless you are in a desert. So the lube shouldn't be going anywhere or building any type of massive debri if it's just in your house and use from time to time. So unless you notice the torque drop dramatically I wouldn't do anything.

Programs like Serato and Tractor uses time coding using a certain pitch on the vinyl. The vinyl itself is one long beep at certain frequencies to ID the placement of the stylus. The program then converts that into a time which can be used to load a song to make it play. Look into it. But nothing can beat the quality of real vinyl. The sound between digital and vinyl.
@HybOj8 жыл бұрын
I agree that pure vinyl is the best, but only in certain situations, I RIPed my whole vinyl collection to 96kHz/24bit wavs during this winter, and than I went thru all the tracks I grabbed in Sony Soundforge. I used borrowed pro grade soundcard and headphones from friend (the card and phones cost more than the rest of the PC). What I found out was, that there are many crackles, even on my near mint vinyls. And I took the painful and long process of removing those crackles manually (no algorhytm). Those damned headphones and soundcard make u really hear everything. Now, after I repaired 100s of crackles and some errors which are on the vinyl, I enjoy the cleaner sound. So, if your vinyls are really mint, than its better, but with some vg/vg+ vinyls, its not so easy to say. Also, u can get static discharges on ur vinyls. That will be non existant issue on digital. I recorded all vinyls wet, to get rid of all static. U cant wet ur vinyls while u DJ... Also, this process of digitalizing and listening carefuly to the vinyls on high end gear made me super paranoid to all crackles, before, I havent noticed em so much on my JBL loudspeakers... I guess once you have heard it, it cannot be unheard. But I will not stop buying vinyls, they the best straight up and down. But those cleaned hd RIPs have also their charm... just sharing and blabbling a bit, thanks for the video Mark! :) PS: I used technics 1210 mk2 with new shure m44-7 needle, than to the Denon dn x1600 for a conversion, outputed it to denon DN R500 recorder using coax (so no aditional conversion) and recorded in those 96khz/24bit wavs at cca -6db. Results are really good.
