7700 very low sound output

[Tony Luffman-cook]

I have acquired a 7700 ,apart from needing new belts and new mmc4 cartridge, it seems to work, however the volume is really quiet ,crank it up to 60 and I can barely hear the radio. It’s the same through speakers and headphones. Any advice as to the culprit would be greatly appreciated, it would suggest an issue with the amp ,would this be a thing for a reasonably competent diy fixer or best left to the pro.

Looking at the connection panel,you should see a round Din socket with light brown plastic plug in it,but with no wires!!!

If you can see the socket but not the plug,then thats what’s causing your problem .

That socket is a port for an auxillary in/out device,eg.a mixer or equaliser,but people often think it’s another input and take the plug out,to connect something like a Bluetooth receiver,which would work,but also interrupt the signals for the other sources.

If your plug is missing,you can source one from the Beoparts shop,that sponsors this site.
