Question about Audio & Video Receivers

Open Question

I have an Altracoustic ACX1000 and need to replace the program potentiometer to the right side of amp and need to get inside to do it. I am mechanically and electronically capable, but don't want to damage anything in the process. Just need to know that I'm disassembling properly. Already removed machined screws from top and sides. Need to know whats next.

As the pots are part of the necessary feedback loop for the final stage, I would recommend that you jumper the wiper of each respective pot to its "full on" position. Problem solved!...accordianman

If the receiver is a new one (a couple of years) I suggest you don't replace the balance potentiometer. It's a potentiometer with rare use so the inner carbon film can't be destroyed. I suggest you to open the case and use a contact cleaner spray (clear, without oil) and spray direct at the potentiometer. Turn it all the way from left to right many times. When it will come dry you will see the diference. As far as the suggestion for clear (without oil) contact cleaner spray, I insist on that because the lubricating oil will cause a trap for the dust and will ask for cleaning again and again. Also for potentiometers with rare use there is no need for lubricating oil.

I think that this solution is much easier than chanching a potentiometer, since the device is not too old.

In case of a problem or clarification, don't hesitate to post me a reply.

SOURCE: Need a part # for

There are many configurations for volume potentiometers - If you remove yours, you can get the serial number off it and go to a local electronics supply store ( or website , like www.radioshack.com) you should be able to purchase the right one. If the shaft is wobbling, you may be able to tighten up the casing by bending the tabs on the back of the casing - make sure you're squeezing the casing closed with the shaft in the proper location. If you have talent ( this part is really challenging for me ) you can straighten out those tabs, disassemble the switch, clean the contacts with a pencil eraser, regrease with dielectric grease and re - assemble. Personally I would just buy another - much easier!!
Good luck either way!!

Receiver Volume changes by it's self


Many possibilities:
  • If the volume using the potentiometer, the potentiometer itself may have been damaged.
  • Bad connections at the antenna connector.
  • There is a loose connection inside, usually between board.
  • There is damage to the electronic components inside.
So, fix it to the experts.

Speaker output knobs producing crackling sound from speaker


The problem is that the potentiometer that the knob is connected to is dirty. This is a common problem with age, or quality of installed potentiometer. (potentiometer is the name of the component that the knob attaches to. It usually looks like a 1/2" long cylinder)

There are multiple solutions to this problem. The first is free & anyone can do. While the unit is off. Twist the knob back and forth quickly and rapidly numerous times. Roughly 10-15 times will do. This sometimes allows for the connections within the potentiometer to reconnect, and remove the crackle.

The second solution involves some handy work. The unit's case will have to be disassembled, and the potentiometer that the knob is attached to must be found. There is usually a relief hole somewhere on the housing. Within this relief hole one can spray contact cleaner. This cleans the contact within the potentiometer which is the cause of the crackle. Once the pot has been sprayed, rotate the knob like in step 1.

If steps 1 & 2 do not work, the potentiometer will need to be replaced. This work usually needs a professional. If you are handy with a soldering iron, it can be accomplished. Look for any particular part #'s on the crackly potentiometer, and then copy these into a online parts catalog. Mouser.com and Digikey.com are excellent resources for finding parts. Upon finding a replacement, it can be swapped out, and provide the user with a crackle free knob.

As always, make sure power to the unit is disconnected. If you are unsure of electronics, please use caution, as dangerous voltages may reside that can cause personal injury.

I have a sansui G9700 receiver/amp. The volume control works intermitantly. Must play with it to get volume. I believe I need to replace the potentiometer F3085. where can I get one? Erick G


The potentiometer doesn't need to be replace, it has collected dust inside causing the intermittent operation. Buy a contact cleaner/conditioner to spray inside it and move the potentiometer clockwise and counter clockwise a few times until the dust inside it is gone.
Check this link to find a contact/conditioner cleaner or you can try spraying rubbing alcohol but this could because alcohol doesn't not lubricants properties.
Let me know if you require further assistance.

My Denon AVR 3903 has a problem in that when you turn it on, first thing in the morning, the volume level is really low then after 30 to 45 minutes later BAM the volume kicks in to where it should be.


Issue with your Potentiometer.... Try to clean it with Air pressure inside your Potentiometer Sometime it full ov dust inside .. go to Radio shack or any store by a Air Spy Can take off your volume Button an spy inside your volume You May have to change your volume wih is call potentiometer if you send it to a radio reapair it will cost you arrond $60 to a $100 dollard to fix

My Behringer BXL3000A bass amp's volume control makes a noise, so what could be the problem?


If the noise appears only when you rotate the control, there is dust inside it. With the amp disconnected from mains, rotate the volume control from min to max back and forth for about 30 times. See if this helps. This is not a definite solution, you maybe have to replace the potentiometer or spray some potentiometer cleaner. Good luck!

Jvc rx 318 receiver


The problem you describe is common to JVC amps. This control has a motor mounted on the back of the circuit card that drives the volume control up or down using the remote control for this system. The looseness of the volume control cannot be repaired. The shaft has separated from the potentiometer. I don't know if JVC has this part any longer but it has to be replaced as a unit (volume control card).
