Is 60 amp electrical service enough for high end tube system

Keep in mind there is a reason your house was originally equipped with a 60-amp service. First off that is 60 amps @ 220volts, which means you have 120 amps at 120 volts. All you may need to run your system is 1 20 amp dedicated circuit of which you may only actually draw 10 amps. You will be amazed what that alone can do for a small to moderate sized system.

I recommend a new service when the old one just won't take any more, or is not functioning properly. Generally speaking most breaker boxes could handle one more circuit for audio no questions asked.

If you ever start tripping breakers especially the main then I would say have it checked out by a professional electrician.

Naturally I recommend you have any and all electrical work preformed by a professional.

I believe most new homes (last 15 years) come standard with a 200-amp service. In your music room you probably only need one or two dedicated 20 amp circuits. One for the amp and some people use the second for the front end and/or a third dedicated 20-amp circuit for digital.

i would say bring an electrition over and put him to work. you do need a 200 amp box i would think. your sound room should have 20 amp lines for each amp . and 20 amps for your preamp. you can never have enough juice.
