dedicated lines will help any audio equipment not just tube amps. i have a dedicated line for my front end and one for my amps. it will stop you from having all of those other electrical devices you have in your house on the same line making all of that noise. it will make a tremendous difference. by far one of the best things i have done for my system's sound
dedicated electrical line
I recently read somewhere that a dedicated electrical line is recommended for some tube amps because of the amount of current they can draw. I have Joule VZN 100s on the way. My home was renovated about 10 years ago - new electrical system was installed at that time.Should I be concerned - not looking forward to trying to explain this one if a dedicated line needs to be installed.
