Turntable problem or bad connection?

Post by reis99 » 06 Nov 2019 17:33

Hi,

Ordered a Pioneer PL-200 online in very good condition, i connected everything and it appears to work and speed adj. seems fine and all but when the turntable is off i can hear a "hum" sound and when i turn it on to play a record there's a very unpleasing sound, like a much more aggressive "hum", it kinda sounds like electricity, maybe it's static? I connected the ground cable and all.

Got an audio recording

That more aggressive noise is the moment i move the arm inwards/outwards to turn on/off the turntable and at the end that's me slightly touching the arm.

Thanks.

I had an older turntable before and it was fine, so it can't be the preamp.

The Devil is communicating his instructions to You. For the sake of Your immortal soul, You must disconnect it immediately and burn it within a pentagram at midnight whilst drinking holy water from a virgins wellington boot, mate!

Seriously its a very dangerous problem and could kill You and burn Your house to the ground, best get a 3ft 2" x 4" and hit it repeatedly with short savage blows. Its how Isis gets You when Your not paying attention.

I'm guessing by your extreme irony that i'm overthinking too much about this? I'm not sure what you're trying to tell me :P

Sounds like a drunk mute getting tazered on a weekend night. Difficult to tell from just listening to that buzzing alone, but it could be as simple as a loose connector or an electrical grounding fault.

Clean all the cartridge connectors and make sure they are tight, be careful as the wires are fragile. Do the same to the RCA plugs. If after doing that the hum is still there, and you bought the deck online, send it back and get a refund. I am saying this as you might not feel confident enough to take the thing apart and look for faults.

If you can't send it back, build your confidence up and take it apart. People here will help you out. Hopefully cleaning all the connectors will help then there'll be no need for the 2"x 4" and isis won't get you.

Are you using a Grado? They are famous for humming.
Or is the grounding tab on your cartridge missing?

Grado...im guessing you're referring to the amp, no it's a TEAC A-R600 with phono input.

So i tried opening it up, i took a look at the RCA/Ground wires and everything looked connected, though the ground wire looks old and rusty, should i take a shot and replace it?

It shouldn't be rusty, even more so as it's made of copper. If you are talking about a rusty connector on the ground wire, then clean it to expose bright metal. It's important the ground wire makes a good connection.

While playing, gently wiggle the connecting cables, including the ground cable, If this affects the noise, then one or more of the cables is bad.

Thanks for replying, i tried gently wiggling the cables including the ground cable, doesn't seem to do anything, also having the ground wire dettached doesn't change the "hum" nor the "shock" sound.

Grado is a cartridge. Inside the headshell, double check both ends of the connections for looseness. Make sure all 8 connectors are firmly attached. They can easily look good and be bad.

Take the headshell off and clean the pins that contact the tonearm as well, can't hurt.

I've tried the same headshell on my dad's turntable and it works fine, i got the feeling this might be something internal.
