Guys,


I have a Cambridge CAV 11 audio vario, the vario works great but I have no
audio. When I open the case there is a speaker connected to the pc board
via a small harness. above that connection there is a 3 prong jumper. Does
this have anything to do with shutting the audio off?


I could use a manual, Cambridge has one online but does not address the
jumper *nor does it have a schematic.

I'd bet the speaker is bad. Have seen this before.

If so, you can use an ohm meter to see if the coil is "open".
Disconnect it first.
