Power Surge Damage

Some components have standby modes or other design provisions which result in some of their circuitry always being powered up, as long as they are connected to ac. Also, anything that can be turned on with a remote control would have some circuitry always powered, so that it can respond to commands from the remote.

Also, if the power or lightning surge is sufficiently strong, it could conceivably jump across a component's power switch.

Solid state components are more susceptible to damage than tube components, not vice versa. Although keep in mind that modern tube components often contain considerable amounts of solid state circuitry in addition to the tube circuitry.

Yes, I would definitely unplug from the wall during potential thunderstorms.

Lightening can even jump across open circuit breakers, so always unplug. It's the best insurance, in fact, except for isolation transformers with derived grounds, it's the ONLY insurance.

The Audience aR1p is a surge protector. Read whats on the website. "The aR1p Adept Response provides surge suppression up to 20,000 amps. Whereas surge suppression devices like the ubiquitous MOV (Metal Oxide Varistor) are sacrificial devices and wear out over time, the aR1p surge suppression does not deteriorate. We have also found that MOV devices introduce grudge to audio and video signal. The surge suppression in the aR1p is entirely silent."

Unplug,unplug,unplug please unplug.I learned this the hard way!!
