Set your meter to DC and measure each preamp main output between ground and positive (center). Ideally there should be no DC on the output jacks.
preamp Luxman 5c50 indicator has gone red DC offset
Hello,
I have just received a beautiful Luxman 5c50 preamp
I plugged it,, turned it up and It sounded great ... but after an hour, I suppose, the led indicator DC offset became red. (normal is white it is said)
and I heard some noise in the LS
I turned it off immediately
Well; I dont know what does it mean but I think it is no good/
Does it mean the preamp is out of service? It is fixable?
What should I do?
Thank you very much
Serge
