Power switch light
« on: September 28, 2015, 01:25:55 PM »
The other day, I powered up my amp (WT-400) at a gig to complete silence. I said to myself, "Hmmm, it can't be the fuse, because the power light is on". Later, after suffering through the gig with a cheezy borrowed amp, I read the manual, and discovered that, for mysterious reasons, the amp is wired to mislead in that way. I don't understand what the thinking is behind this.

My request for the future would be to give us a way, other than through complete silence, to know that we have blown the fuse. Seems to me the most straightforward way would be have the switch NOT light up.

Thanks,
C:-

The light simply indicates that the unit is receiving power, which tells you that you don't have a problem with power supply or power cords.  If the fuse blows there's no power in the amp circuits by which to activate some other warning light.

Of course if the light were not there and you opened it up believing that it was not receiving power when it was... goodbye C!
