Question about Audio Shelf Systems

1 Answer

My stereo receive hums annoyingly when I use my record turntable.

I have a old Technics SL-D2 turntable and JVC RX212 Receiver. If the receiver is on, the humming begins as soon as I select "PHONO." If the receiver is off and set to "PHONO", the humming begins about 3 or 4 seconds after I turn on the receiver. The commencement of the humming is sudden, not gradual.

    I turned over the non-polarized plugin for the turntable. The humming persisted. Not as loudly, but still annoying. I did learn, though, through this process that there remains a hum whether or not the turn-table is plugged in to an outlet. The stereo only has to set to the PHONO position. It is a bit louder with the turntable plugged in. I also noticed that when I unplugged the leadins from the turntable to the stereo (with the stereo on and in the phono position) I got a very loud hum momentarily as I did so.



    I'm baffled.

Just a suggestion, make sure the power outlet/s is grounded and that the polarity on both plugs are correct.

Why speaker hum when connecting preamp out cable to Receiver


An audio hum like you are describing is usually from a bad wire or connection. It could be a filter capacitor from a power supply too. Try other cables to see if that helps.

I have a new Yamaha RX-V365 receiver and an older technics turntable, regardless of input setup I cannot get any volume from the turntable, yet all other inputs like CD, Tuner are fine....amp issues in...


Some turn tables do not have a built in amp, especially the older ones, the sound goes from the needle to the output. If the amp your are using does not have a designated phono, turn table, input it may not have the turn table pre-amp built in. Some turn tables have to be grounded to the amp to work properly.

Hi, I have a technics stereo system from 1986.


If the turntable is belt driven you may have a stretched and slipping belt that needs replacement. This seems most likely and is simple to fix. You will have to lift off the turntable to see the mechanism beneath. It may be held on by a nut or clamp. A web search for the model name and "dirve belt" may yield a replacement.

If it is driven directly by a motor without a belt, the motor is probably dying. Replacement more involved, expensive, and hard to justify, unless you're really into vinyl.

Speakers humming. No reception.


The audio amplifier in the unit has failed, and that's what you smell. Turn it off and quit using it immediately - it presents a fire hazard. It might be possible to replace the bad parts. Depending on what it cost, you might want to take it somewhere for a repair estimate, but be prepared to learn it might not be fixable. Often the burned parts damage the circuit board as well.

Usually this happens in small stereo systems because of running them at high volumes for a long time. If you want to listen to loud music, you would be better off putting the money into a higher-power system.

Troubleshoot auxiliary equipment


There is no Phono input on your JVC.

What TT are you trying to hook up? If it's a traditional one you would need a preamplifier to boost the tiny signal from the cartridge to a suitable level for the AUX to use.

If you have an old traditional receiver with a Phono section hanging around you could rig something up between it and your JVC.

Plug the TT into Phono on the old receiver. Run RCA cables from any Tape REC output to the AUX. Done.

Record player works but no sound from speakers


I've had this happen before, and it is caused by your ground wire not being hooked up. Depending on the type and age of turntable, it will have an additional wire (the ground), that needs to be hooked up to either a screw or some sort of opening similar to your speaker wire hookup. That should take care of the problem. If you don't have a ground wire coming out of your turntable, I don't know how to help, other than figure out how to ground the turntable.
