I love my Model One, but after I'd had it for a year or so, the volume control started acting up. It no longer goes gradually up and down...it seems to fade out at certain positions on the dial, especially the lower volumes.
I can make it work by sort of twisting high and low until I find a volume I like coming in clearly. Very inconsistent, and kinda annoying to find the "sweet spot" for whatever volume I want.
By the way, I wondered if this was a function of the radio setting, but I hooked up my iPod to it and it did the same thing (though I could more fluidly adjust the volume with the iPod control in this case).

It sounds like there may be a problem with the switch or the connections between the switch and the circuit board. Here are a few troubleshooting steps you can try:
Clean the switch contacts: Over time, the contacts in the switch can become dirty or corroded, leading to poor or intermittent connections. You can try cleaning the switch contacts with a small amount of contact cleaner or rubbing alcohol on a cotton swab. Be sure to unplug the radio from the power outlet before attempting any cleaning.
Check the connections: The switch may not be making a good connection with the circuit board, or there may be a loose wire or solder joint. You can try opening up the radio (if you're comfortable doing so) and checking the connections between the switch and the board. Look for any loose wires or solder joints, and gently re-seat or re-solder them if necessary.
Replace the switch: If cleaning and checking the connections doesn't solve the problem, the switch itself may be faulty and need to be replaced. You can contact Tivoli Audio customer support to order a replacement switch and get instructions on how to install it.
I posted this tip elsewhere but the FixYa site is, shall we say, challenging.<br />
After years of use my Tivoli PAL started having volume problems. The audio began popping, volume changed erratically, static, booming, almost feedback sounds.<br />
In my case, and others as well, I've gleaned, the problem was the volume potentiometer. Apparently it oxidizes over time and the poor electrical contact is the reason for the erractic audio.<br />
I'm not an electrical repair kind of guy, so this isn't pretty.<br />
The volume and frequency controllers are secured to the knobs with metal collars. I pried the collars loose and got the horizontal board off, I sprayed Stabilant 22 into the volume pot. There are other electrical contact cleaners as well.<br />
Put it all back together. Let the flud dry. Good as new.<br />
Good luck.
It's most probably dirt on the carbon track of the control causing the problem. There aere dedicated aerosol sprays to clen them, and you local Radio Shack could have some - if not, WD40 sould work but will leave behind a greasy residue that may trap dust and cause the problem ot reccurr again.
Assuming you can purchase the cleaning spray, you will beed to dismatle the radio far enough to gain access to the rar of the volume control. There are openings in the cover where the leadouts emerge, and the cleaner can be sprayed into the control from there. Then simply rotate the control back and forward fairly quickly over the full range of rotation, reassemble the radio and it should be nice and quiet again. Note you may need to rotate id a dozen times or so if it's really dirty, and in extreme cases it may even need an additional squirt of cleaner :o)
Disconnect the AC outlet and open the main Tivoli unit.
Look at the back side of the volume switch and you will see a power switch piggy back onto the volume control.
You can bypass it or get the correct value Potentiometer + SPST switch.
Use an ohm meter to meter the both end of the potentiometer and if it's 10,000 ohm or 10k then just go to Radio Shack and ask for
10K-Ohm Audio Control Potentiometer with SPST Switch
Model:271-215
| Catalog #:271-215
It's a direct replacement.
If the ohm read is other then 10K then you will need to order it for an electronic supply house.
Tivoli makes great radio.....if you want to sell it I want the first dip.
I had the same problem and was able to repair it quite easily. Only thing needed is some basic soldering skills.
Problem description:
Suddenly a quite loud and disturbing (scratch/screech/buzz) noise appears.
Sometimes the noise is gone but it reappears sooner or later.
Changing volume or radio band / input (am, fm, aux) does not affect the noise (even on volume turned down all the way).
The signal coming out of the Headphones / Rec Out plug is not affected.
Cause:
Cold solder joints
Solution:
Unplug from mains
Remove back panel (the two black screws next to the plugs in the
center). The back panel sticks quite firmly, so it might help to remove
the front panel first (the 4 screws in the corners) and carefully press
out the back panel from the inside. (The other two (silver) screws are
used to attach the transformer to the back panel) and need not to be
loosened.)
On the circuit board at the back panel locate the plug that goes to
the speaker (is says "J2"). Check the solder joints. In my case, looking closely, I could see that they're not good anymore.
Renew the joints by heating them up and applying some fresh soldering
tin. I also renewd the joint from the wire bridge next to the plug. Just
check the other solder joints on the board.
In my case afterwards the problem was gone and the device is working properly again.
This is an easy fix with a can of volume knob cleaner i think its called. You should be able to get it at radio shack. You just spray it into the volume knob and let it dry. The instructions are on the can.
I noticed the same problem after I had moved. Hadn't had it before. The solution was easy in my case. (It took some time to accidentally figure it out though). I flipped the power cable around 180 degrees / upside down and re-connected. After this the volume worked as before. This was the model with European power plug.
Radio Shack does provide a volume control cleaner that you could gently spray to clean the contacts, but you may simply have a defective knob. (The first S350DL I bought had a defective volume control.) Don't hesitate to call Eton Customer Service either.
I hate to say this, but I've become a little wary of buying radios at Radio Shack. I have a suspicion that occasionaly radios that are returned get "recycled" back into stock rather than sent back to the manufacturer. I had to return 2 radios directly to Eton / Grundig after getting back to back defectives at RS.
I have the exact same problem with a Tivoli iSong book.
I have the same problem and plan to have a closer look.
My volume goes from silent to as loud as it gets with nothing in between but some scratchy static noise when turning the volume nob,
