Got a used beolab 7-2, as suspected from its 30€ listing price it didn’t work. The diode under the rubber cap in the back of the unit shows a red light when plugged in, then switches to orange immediately when power link cable is connected. So I measured the resistance of all the speakers, and found that one tweeter showed a 0 ohm reading. This would likely be the culprit- but as this is a very low cost situation I would like to verify this before ordering a new tweeter. The orange light persists when the tweeter is removed- I am not sure if this is normal- or if the unit should be able to turn on without a tweeter connected.
I am not very savvy when it comes to electronics, so forgive me if I am making any obvious mistakes- but if anyone has some advice that could help me confirm that the the tweeter is not a secondary casualty to a bigger problem it would be greatly appreciated.
