I was asked to repair what I believe is a Klipsch Amp. It has no model number, the control panel is black with Klipsch Inc on it. Also says "A Legend In Sound." Has a power switch, on/off/auto, Phase switch 0 or 180, Av switch +3db, Highpass switch 40 hz or 80 hz. Rca line out and in left and right, plus sub. Two knobs, Lowpass 40hz to 120hz and Level 1 to 11. Speaker hook ups left and right Hi level out and Hi level in.
The only numbers on this panel are 118294 in small print below the 120 AC 330 watts 60 hz in plug. Any information or help would be greatly appreciated.
TIA
