Electrical Question


I normally disconnect my power cords from the wall on my amps when not home or not using. I now have a amp where access to the outlet is not easily accessable. I assume the local amp on/off switch will protect from power surges etc., but what about lightning strikes ? . Will the on/off switch protect the amp ? . Can lightning "jump" the switch and cause damage ? ...... I do not like to use power conditioners/surge protectors with my amps....

Ask Lee Trevino. If lightning can strike a tree and then jump or arch to the person standing several feet away, it should be pretty safe to assume a lightning strike can easily jump the switch inside the amp and cause serious damage or explosion.

Kinda' funny, I saw a picture recently of a mattress torn apart and charred because lightning went thru the roof, attic, ceiling straight down to the mattress where nobody was sleeping. It looked like a grenade exploded inside the mattress. I guess nothing is safe when it comes to lightning as it always depends on it's intensity.

Some electrical companies offer as an option a whole-house surge protection mechanism. These may or may not work, but if you have one and your things are damaged by lightning, they typically reimburse for $10k to $20k of the damages.

Kinda' like an insurance policy and I do not believe these protectors affect sonics. I had one installed 4 years ago for $5 per month.

A few years back I was working with somebody whose house was on a hilltop. His chimney was struck by lighting and exploded. Half of the appliances and electronics in his house needed to be replaced as a result. He had the whole-house surge protector installed. And the electrical company reimbursed him for all damages.

So at least we know the insurance part of the whole-house surge protection system works.
