Protection needed for amp?

I live in N. CA, where power outages have become more frequent.

As a result, we've had a propane back-up generator installed that comes on automatically when the there's an outage.

Question: If my system is running and power is suddenly cut off due to an outage, then suddenly restored by the generator, does this pose any danger to the amp?

My recently purchased Hegel H390 is the most expensive component I've ever bought and I'd prefer not to replace it.

If it sounds like I know nothing about electricity, it's because I don't. 

When I power up the amp, there's always a delay, then a loud click, before it's ready for use, whatever that might suggest. 

Thanks in advance!

This outlet adapter requires the user to press the reset button after the initial plug-in or a power outage.

Thanks for your response. I'm sorry but it's not clear to me whether you're saying  every system needs surge protection as a general rule or whether it's particularly apropos in my case. Could you please clarify? Thanks!

Would something inexpensive like this work or do I need to spend more?

Hi OP

Yep, that strip is great. You can add features but not protection. Meaning, you can get a Furman with balanced power, or voltage regulation but they aren’t safer, just more feature filled.

 

I’m sorry but it’s not clear to me whether you’re saying every system needs surge protection as a general rule

A whole house surge protector will keep your house from catching fire and protect your major appliances like your air conditioner, water heater and stove but they have relatively high activation (or clamping) voltage so it is always recommended that you use a strip at the appliance itself if it’s delicate and of course, based on the cost to replace it.

What you should put on a surge protector is a value and risk judgement. You have a 30" TV in the guest bedroom and you don’t feel like spending $50 on a surge protector, that makes sense. My PC however which is not only expensive but may have work that is not easily replaced is definitely on a strip.

It's also a location judgement. I'm in South Carolina so we have regular serious thunderstorms that routinely take out communication equipment and unprotected appliances.  You on the other hand have PG&E and there is no way I'd trust them. :-)
