I recently acquired a used Amplifier that was very dirty.I am no stranger to cleaning out dirty audio gear, and so I took mytrusty Hoover and carefully vacuumed out all of the fuzz and lintI could see. I also used a small paintbrush as a miniature whiskbroom to get in the tighter areas.I was very, very careful not to disturb any wiring connections.I carefully put the top cover back on and used the amplifier for acouple of days with no problems whatsoever.But now I have noticed that the digital wattage readout on the frontof the amp no longer lights up. I believe that it did light upnormally after I re-assembled the amplifier, but I still can't helpwondering if I did something to break a connection somewhere.Does anyone have a schematic for this amplifier?Is this a common problem on these amplifiers?
