100%. That last bit of b-roll I’m actually connecting the ground to a phono pre-amp... I just forgot to film the part where I actually say it! Will redo and re-upload when I can. Thanks!

Sorry to be so late getting back to you on this. If there was ever a turntable to bring back to life, it's a Dual! I've got two that I refurbed, and they are my new lust objects. If there is a chassis screw you can back out on the receiver, I'd try that, first. Not sure you need to solder anything. Sometimes, just taping the bare ground wire to some clean metal on the receiver will do the trick. Keep 'em spinning!

Sorry for being so late in getting back to you. Some things to try: make sure the RCA Cable connections are clean at both ends (the male ends from the phono and the female end on the speakers). Check also the connections at your audio cartridge. I've pulled cartridge out, cleaned the connections and had the buzz disappear. Not exactly sure what the configuration is on your model, but at the very least, give it a wiggle and make sure everything is tight. Good luck!

You're welcome! Thanks for reaching out.

Yeah man, sometimes it's just a guessing game ... pull a plug here, switch a location there. An easy first step is to switch out receptacles. If you've got a turntable plugged into a switched outlet on the receiver, for example, pull it out and try in a wall receptacle. Moving stuff around between power sources can sometimes take care of a grounding issue or get enough distance between components to take care of interference issues. Good luck!

Hey Matt - It's not metal, per se, that creates the ground. It's the fact that the receiver is plugged into an electrical outlet that is grounded (your home's electrical system ultimately grounds out to a metal rod in the earth). Best bet is going to be to ground your turntable to the receiver. Keep 'em spinning!

@@DeafManVinyl great explanation, thanks so much

similar situation is in my case, my turntable chasis is made from wood, no grounding.

Awesome!

Connect it to any large body of metal and it should solve the issue for you. You can test by taking the ground wire and touching it to various metal things to see if it reduces the hum noise. If it works, you can use electrical tape to keep the end of the wire in place.

@@DarrinLin thanks 🙏😊❤️🐼 have a wonderful week !!

You're welcome!

Have you played around with "proximity?" So, moving the components apart, even plugging into operate outlets? I've had that help a time or two.

There should be a grounding post on the stand-alone pre-amp. That's where it goes. Good luck!

I'd start at the start and make sure the pins on the cartridge are shiny-bright clean and the connectors are snug. Good luck!

By all means, if the hum goes away when you disconnect the ground, then leave it off.

It may actually make things worse. Huh?? Yes. Another source of noise (hum) can come from what are known as grounding loops. Everything is 'grounded' with wires yet there is still hum. This is likely because you are on a circuit in your home that is not dedicated for just your audio system. Other household items are sharing the return and ground with your system --- especially the ground. Phono components are very sensitive due to their need for amplifying small signals (from the cartridge) by many orders of magnitude ... usually anywhere from 45 to 65 db. Compared to other components, this is huge. And any small amount of noise will get all that amplification too. And introducing that ground (third) prong may bring any noise on that shared ground circuit into your system. So what do you do? Well, you can always try it and see if anything positive happens. Make sure that the little tab that sticks out from the adaptor gets your turntable's ground wire attached somehow to it. But if it doesn't work or the noise gets worse you can try putting your components on a dedicated circuit that has NOTHING else on it --- and runs straight to your panel box. And then make sure your panel box has TWO long copper rods driven into the Earth at least 6 feet apart that connect directly to the ground lead inside. It's what I had to do to fully solve my ground noise. But I was in the market for a new panel box anyway.

Hmmn. I've not tried that. Do you mean attaching it to the set screw on an outlet (the one that holds the cover plate on)? Seems like that might work.

It could be "the arm" as in poor grounding of the cartridge. Two of those angel-hair wires coming out the back of your phono cartridge are ground wires (left and right). Sometimes, you can get rid of hum by carefully pulling off the wires and cleaning the contacts (pushing the pins into a pencil erasure is an old stoner trick from back in the day). I use a cleaner called Deox It to clean up contacts. Then, give the connectors a squeeze if they are not fitting snugly back on the pins. Let me know if you get to the bottom of it.

Hey, sorry to be so late getting back to you. Are you plugging the turntable power cord straight into the turntable? If so, I'd experiment with plugging it into a separate (wall) receptacle and play around with placement to see if you're getting some proximity interference.

Duals are great turntables! I've got a 1229 and love it. You might try attaching a ground wire to some (non-moving) part of the chassis, coming up from the bottom. Mine is pretty easy to access. I'd also make sure the connections from your audio cartridge are good (the pins are clean and connectors fit snugly). Good luck!

@@DeafManVinyl Thanks. I'll try all the above.

Hey Elias - What kind of turntable do you have? Is there a ground wire or ground connection on the back? Regardless, a good first step is to try plugging the turntable and the powered speakers into different receptacles (turntable into one outlet and then outlet into another). Let me know about your turntable model and I'll see if I can help further.

Man, I'm having a hard time following you on this. If you want, send me a quick video that captures the sound.deafmanvinyl@gmail.com

i am pretty sure that your model uses a ground wire. It is usually a very small hole next to your rca outputs. it should be a needle ground wire like my old technics. One end is like a needle and the amplifier end is the U shape screw type to hold it.

Hey Tom - why are you wanting to ground it? Are you getting some hum? I'm thinking that the LP 120 doesn't have a ground wire, does it?

Hey - Sorry to be so late getting back to you in this. Without a ground wire, I'd suggest playing around with positioning (i.e., try separating the turntable away from the receiver, plug them into separate outlets). Another cause of hum is bad connections from the audio cartridge to the tonearm. Check those (but be careful, the wiring is like angel hair!). You can clean them with something like Deoxit. Or, use the old school way (a pencil erasure).

have you plugged your amplifier and turntable on the same outlet? if you use different electrical wall outlets big chances you will get a loud hum. Problem was fixed for me, i have a vintage technics TT on a vintage Marantz 2240 amplifier.

@@boromir_8428 the equipment is plugged into the same circuit. There’s for duplex receptacles on the circuit. It’s basically by its self in the basement. I ran emt pipe and installed a separate equipment ground wire in the conduit. I think its just the old equipment or maybe the cartridge? It’s not horrible just a bit annoying

@@anthonyelectric6045 hum... maybe it`s your cartridge and/or your ground wire is bad. But you know it is ''normal'' to hear a little something when you raise the volume having the stylus in the air, not touching the record but this sound is quite low usually.

@@boromir_8428 so today the turn table arm wasn’t working properly. So I took the base off and retighten a Allen screw etc. low and behold one of the ground wires weren’t hook to nothing. Quiet as a mouse now after putting it all back together. Thanks for your help 👍

@@anthonyelectric6045 ahhh, no wonder it was noisy! good for you and your welcome : )

If the humming is coming through only one speaker (channel), the problem might be with the connection at the audio cartridge, which powers both a left and right channel. I'd carefully pull the wires off, clean the pin on the cartridge and firmly re-attach (do them one at a time). Good luck!

Thanks for this I'll give it a go

Wow. Not sure I'd sweat the 16 rpm not working. That's a super obscure format that was used a lot for spoken word and radio broadcasts. As for the hum, is there a ground wire visible (often green) or an obvious place to run once?

@@DeafManVinyl not sure the needle arm may be where the short. If I could trust someone to fix it I would sent it

Check your connection at the cartridge. Maybe they got jostled doing moving. Everything should be tight and clean.

@@DeafManVinyl My turntable had a ground. I did try grounding it to the reciever but, it didn't work. I'm thinking about upgrading to a reciever that has a phono imput.

@@DeafManVinyl you might be on to something with the cartridge.

You can especially hear it between the tracks on an LP. And my turntable is brand new>

Not sure about that one, man. Thumping sound is not typical. Sorry to not have the answer for you. Might want to play around with placement, or put a rubber mat under the turntable and see if that helps.

Check this out (a method that I was not familiar with). If your not getting hum, don't worry about grounding (some modern turntables don't require it and hum can be addressed by addressing proximity issues.) www.google.com/search?client=safari&rls=en&q=rega+2+turntable+how+to+ground&ie=UTF-8&oe=UTF-8#kpvalbx=_6SVhY-G_DcPIkvQP7-K0gAY_39

Rega turntables don't have a separate ground wire. The ground is connected through one of the phono connector signal grounds. It works well. There is no point trying to connect a separate ground wire, at best it will achieve nothing, at wost it will create a ground loop and you'll get horrible mains hum.

Just noticed my question was already answered.

Hey George - You might need to get inside the unit to make a connection. See electronics.stackexchange.com/questions/163457/what-is-the-purpose-of-a-turntables-ground-wire. I'd also play around with proximity (move it away from anything else electronic) and try plugging it into a separate outlet (check polarity if it is an old-school unpolarized plug). Good luck!

Have you tried plugging into an outlet separate from the rest of the system? Move it away from the other components?

​@@DeafManVinylyes I have unfortunately nothing's worked

Yeah, grounding issues can be befuddling. Have you thought through "proximity' issues (e.g., the turntable and amp too close together)? Are the cartridge connections clean and tight (and correctly installed per the color-coding)?

What else do you have in the system? A receiver? A pre-amp and amp?

@@DeafManVinyl I have a Denon reciever 3312, Denon brp 1610, Denon CD 5-disc, and a Monster power conditioner. As soon as power yp the TT, the hum goes away.

Well, not all turntables need a separate, external ground. Some have rubber and plastic parts that negate the need for it. But it there is a slot in the back that says Gnd or has the three-line ground symbol, you're going to want to ground it -either by rigging a ground wire or going to someplace like www.turntableneedles.com and getting a ground wire made for that model. Good luck!

So, if you have a ground post on the back, that's the place to connect. Sometimes you can literally tape the bare ground wire to the back of the receiver and it'll work. Good luck!

Wouldn't dream of it!
