Question about Audio Players & Recorders
After accidentally unplugging the stereo while playing at a moderate-high volume (less than half power), the volume stopped working. The stereo emits a very low and weak sound with a fixed volume level (impossible to turn up or down), and impossible to hear from the speakers (it is so low that you can only hear it plugging in headphones). The stereo is 10years old and this has never happened before. Any idea of how I could solve the problem myself or where to go in London? Thank you, Ross

The headphone is tapped before the final stage of the amp, so knowing that those work properly helps to isolate the problem. I think that this model uses an IC for the voltage amp section prior to the final amp stage. That being said, the IC is probably an UPC2598 (if memory serves). I'll confirm tonight. Try resoldering any connections that appear to be grainy or have rings. Let me know what you find.

SOURCE: PINs for high level input
You did not specify exactly which Jensen amp you have. None of the Jensen PowerPlus series I found had high-level inputs. You can go here and select your amp to download the manual. They should also have the connector for speaker inputs.
Most amps that have both high-level and RCA inputs allow you to use one or the other, but not both at the same time. If your head unit has RCA ourputs, those would be the ones to use, because they generally provide a cleaner signal to the amp with less noise.
Hope this helps.
