Hi I'm new here & in need of some advice! My Quad 66/606 amps have recently been reconnected after room decoration but seem to have developed a background hum along with a slight loss in power. This is happening through all inputs, CD, Ipod, radio etc. The speakers & cables are all the same as were working before. Help please.
