Question about GE Superadio III AM/FM

Volume control shot

I have removed the broken pot (actually on a Superadio II) - but there are no numbers on it that my local electronics store can use as a guide for replacement. Where can I get a replacement part? Thanks winstephen

I can't find info on the parts online, however if you email as detailed of a description of what you need to: thom@insight.rr.com they can probably help you. They're quite good at finding parts.

Low volume one speaker


It seems likely that the pot (volume control) is dirty. with a slider you can normally get fluid down the side of the knob, your's is a rotary control and you sometimes can do it round the shaft of the pot but more often have to spray it in where the connections go into the pot. You'll need some contact cleaner spray which you can get online or from an electronics store, get it onto the pot track and then take the pot to each end of its travel a few times, this'll probably sort it out until next time. If you're taking it apart it might be worth just getting a new and better pot and soldering that in if you are hand with a soldering iron. The ones in Mackies nowdays are pretty sh1t.

Volume control on GE Superadio


Although the pot is broken it may just be the wiper part & you can try measuring across the outside terminals (if broken disassemble)with an ohmmeter (DMM). If you get a reading say 10k ohms then you know what to order.

I need a volume control pot. for a RCA WHP150C 900MHz wireless headphone. I cannot find a circuit digram nor do not know how to order it by part number (since I don't have the circuit diagram). I need a...


Hello Arthur.
If the pot has an engraved / embossed / screen printed value on it you may also be able to buy an exact replacement from your local electronics component stockist.
Otherwise take it with you as a sample.
Pots are standard values, so most component stores will stock your one.
This will be cheaper and speedier than ordering one.
Regards, Clive.

The volume control on my Gorilla GB-30 amplifier crackles when turned, but the actual volume never changes. Will a new control switch fix the problem? Are manuals available?


There likely is another problem, possibly a cracked circuit board or bad solder at the control. If the control worked at all, there would be some change in volume. Take unit in for repair.

The volume control is not working... even when the volme is "off" it is still on


Chances are the resistance element in the volume control has broken. This is COMMON if the control knob gets smashed some way.

A less common thing would be broken solder where the control is soldered to the circuit board. This would be obvious once the board is accessable.

Servicing involves removing the chassis and replacing the potentiometer.

Yamaha RX-V800 volume control


i would say that the component that controls the sound level (called a potentionmeter) or (varible resistor) is either broken or faulty....you will need to remove the cover and inspect the area around the volume control just to make sure it is not broken or that any wiring has just become dry jointed....if all is good then what i would suggest to do is to find out the value of the pot...normally there around 10-50K then youll need to get a replacement...if this still dosen't fix it or your confident enough to look or fix it yourself i would take it to a local electronics repair shop....remeber to disconnect unit from power before removing cover hope this helps,ben

Volume control pot is bad. Tagged VR1 on PC


Before you replace the pot, try cleaning it. Use electrical contact cleaner such as:

- CRC QD Electrical Contact Cleaner (available at many auto supply stores) - www.crcindustries.com
- Caig DeoxIT (available at Radio Shack and electronics supply stores) - www.caig.com/

Spray the cleaner liberally in the pot (spray where the shaft meets the pot, and if possible, into any holes on the back of the pot), and rotate the shaft repeatedly. Repeat several times.

If the pot is still intermittent, it can be replaced, but you need to replace it with a compatible part, and the job will require some soldering skills to prevent damaging the rest of the circuit.

Make sure you get an appropriate replacement. You need a replacement pot with the correct resistance (measured in ohms) and taper (linear or analog). Typically, the value of the pot is marked on the back, and will read something like "103A" or "10K - B". 103 or 10K indicate the resistance in ohms, and "A" or "B" indicate whether it is linear or audio, respectively.

Your best bet is to desolder the part and take it to a local electronics store for a replacement. If no store is available locally, replacements can be ordered from online stores such as:

- Mouser.com
- Jameco.com
- Digikey.com

Feel free to post the numbers on the back of the pot if you need help locating an appropriate replacement.


(Note that the convention for labeling taper has changed over time - getting the wrong taper should not damage the equipment, but will probably result in the volume control to seem "not smooth.")

Gain knob produced crackling sound


This is usually caused by oxidation in the potentiometer (fancy name for your volume control, also called a pot). The solution is to buy a small spray can of tuner cleaner, then unplug the amp and partially extract the electronics chassis from the case -- usually by removing screws in the top (but NOT usually the top handle screws), then gently sliding the chassis forward until you can easily see and reach behind your gain knob. You should see a squashed metal cylinder attached thru the faceplate to that knob -- that's the pot. It will probably have 3 wires attached -- don't worry: these never have voltages high enough to feel even when the amp is on. Either near where these wires are attached or elsewhere on that cylinder there should be one or more small holes. Using the small plastic tube that came with that spray can of tuner cleaner, spray a small amount of cleaner into the pot, then turn the gain knob from maximum to minimum and back several times. I usually do this by plugging the amp into a receptacle and moving the knob this way BEFORE using the spray, listening for the noises, then I spray it, manipulate the knob as described and hear the noise disappear. Unless you're confident about doing that, DON'T! Instead, slide the chassis back into the case and plug the amp in, then see if the noise is gone. If so, put in all the screws and you're done. If there's a noticeable improvement, but still some noise, move the knob bank and forth a few more times to see if that fixes it; if not, unplug the amp, slide the chassis out again and repeat the spraying procedure one time, then reassemble the amp and plug it in. If your problem is still not gone, you'll have to replace the pot. If you know how to solder WELL, you can order another volume pot thru a Marshall dealer or online, OR you can remove the pot and take it to a local electronics store where they can probably find an equivalent potentiometer at a lower price than the genuine Marshall part -- be sure to ask for one with "an audio taper" (a logarithmic change in resistance that corresponds to how audio amplifiers control sound). Good luck, and please post your results on this website.

Two-way radio speaker too loud -- will not allow lower volume


I had the same problem with a number of the radios we have here. The trouble was the volume control pots had broken loose from the circuit boards. Some I was able to repair by resoldering and some needed new pots. We got parts from a local Motorola distributor.

Superadio noisy volume control


have you tried just cleaning them? even though they are probably supposed to be "sealed", most of them are not. if you purchase a can of pressurized tuner cleaner, radio shack used to carry it. saturate the volume control while turning it. i usually wrap the unit with paper towels as to not get the rest of the board. i also usually put on my safety glasses. you will see why. i am usually surprised as this works well with 90 percent of them i do.
