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.

Hard to give you a definite answer without knowing all the specifics. From a design standpoint your system is capable of supporting 10,550 watts continuously and may be adequate if there are no major electrical appliances connected such as a range or dryer.

Typical problems with 60 amp services usually involve the lack of adequate branch circuits. This usually is most indicated by blown fuses or tripped circuit breakers.

I would recommend for serious jazz listening a least one dedicated line for your audio components. This of course requires that the existing service have the ability to add the needed line(s). Even if your service appears full, oftentimes an auxilliary box can be added via existing expansion lugs. You may not need a full service upgrade if expansion lugs are available.

As far as costs are concerned, in the midwest full electrical service upgrades start around $2000 for the very simplest and usually go much higher.

A reputable and knowledgeable electrical contractor is really your best resource to answer your questions.
