Hi,
I've reviewed other posts on the forum for the Tivoli Model One but these are nearly all focused on the issue of hiss/scratchiness and tuning slippage in the device and diagnose cleaning/replacement of the varicon in the unit.
I'm getting a different issue so, before I rip it open, I'm keen to get some advice on possible causes. The radio now emits white noise on all input settings (AM/FM/AUX) at low/med volume. When the volume knob is turned up very loud the noise dissipates and the audio signal comes through. Switching internal/external antenna has no effect. Listening through the headphone jack doesn't produce as much noise at low volume but still requires volume to be at top level to let the audio come through.
Given the variability, is this pointing to shorting in the volume potentiometer at minimum settings or are there other things I should look at (e.g. cracks in PCB/bad solder joints). It basically started happening "overnight" and the unit wasn't dropped or damaged in any way.
Any help appreciated.
