back ground noise with my wilson puppy8


CAn anyone tell me how to reduce background noise with my Watt puppy8 whcih are connected to lamm1.2 and BAT 32SE as preamp. All of components are hooked to single 20amp Shunyata power conditioner. Would out of market power cable for each amp help???

Update: BAT recommended changing Htubes as older tubes tend to emit "radio" like cracking/hiss sounds
Update: Was electrical noise that comes on during day time. BAT preamp running very quiet now
It may your ground feedback, so try to take out either your pre or power amp (i.e, power cord earth connection). It work for my Krell/ Manley combination (My amp is operating without ground.)
