SOURCE: I have a 1963 RCA

Hi pab69874

Have you been able to test the speakers to determine that that is the problem? Parts are quite available for vintage gear, you just need to know where to look. If the speaker drivers are faulty, if you can give me the make and model number off the back of the magnet, I can source them for you.

regards

SOURCE: I have an RCA Victor

There is a filter capacitor in the power supply near the power transformer that is open. The capacitor must be changed to get rid of the hum.

I get an intermittent loud hum using NAD AV316 amplifier, with stereo speakers(B connection) with phono input from Dual 606 turntable. Hum increases/changes when tone arm on turntable is touched.


The hum of course is the 60 cycle line AC voltage. Make sure that the routing of the AC power plug is as distant as possible from the stereo RCA cables.

The most likely problem is the connection of the phono cartridge to the wires in the arm. These connections usually are silver plated and become oxidized creating a bad connection. Remove the cartridge and using a fine eraser polish the connections. There is a ground connection that makes the five wire connection. Be super carfull these terminals are very easy to break

The phono connections to the stereo is very low voltage subject to interference. The connection to the magnetic pickup at the tone arm is low impedance and is inductive. Any poor connection between the cartridge up to the AV316 will produce this hum. Continue to check connections and swap cables with a known good to resolve.

I have switched the left and right cables to ensure that the cable is not the problem.

Hope this helps?

Both Technics SL1210 mkII's loud hum and almost no sound...


You seem to have some feedback hum from somewhere. I would think it might be caused by a faulty connection somewhere.

Technics sl-BD20D turntable, attached pre amp but now have a loud hum, noticed there is a round jack with a pin in it next to the 2 outputs. Is this for grounding? Are there special cables that fit that...


Hi, Yes your turntable needs to be grounded to get rid of hum. Make sure that your turntable, preamp and amp are all powered from the same point. Most preamps do not have a grounding connection on them and when they do it is normally on the same side that the rcas from your turntable connect too. What is the make and model of your preamp. I will check it out. To earth to a preamp without a grounding connection do this. Take the grounding cable from your TT and slip it in the side of one of the 2 rca connections as you plug them in. That will ground your TT to the amp. If it doesn't then swap the ground lead to the other rca. Cheers John. Styluscity.com.

I have recently acquired an old rca victor victrola model tpm-111 console combo record and radio. i would like to know what cartridge and styli options i had.


I don't know the model in question, but all you need to know is what type of cartridge can be used with the amp. Ceramic or Magnetic? Once you know that you can fit any that will phyiscally fit in the headshell of the deck of the type that can be used with the amp.

Buzz....hum problem from turntable....


Did you ground the turntable? Most of them have a ground wire located somewhere that connects to a screw on your electrical outlet. You could be getting hum from your pre-amp if it is a low quality one. Try unhooking the pre-amp, if that is the problem you won't hear the hum. If the turntable ground is the problem you won't hear music with no pre-amp but you will still hear the hum.

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.

Have a B&O RX-2 with mcc4 and loud hum


Possibly check the wires on the cartridge, make sure none of them are touching and are not bent to badly, are all the connections tight? some cartridges require plastic sleeves over the connections, this insure they don't touch and
avoids resistances between them. Also some cartridges are not compatible with certain model turn tables.Is it universal? Also you my need a mixer most turntables don't work with amps alone. Mine don't. Usually most models you attach the ground wire to the mixer. A mixer boosts table power and take stress off the amp. Hope this helped! good luck!
