Surge protector without line conditioner


Hey Guys 
I have a 300 watt krell class A amplifier. There was a short and they are replacing the transformer.

Anyways, Krell told me I can use a surge protector but make sure it is not a line conditioner.

Any recommendations for a surge protector since most the best one have line conditioners?Plus I have no intention in spending more for a surge protector than the amplifier is worth.

 I appreciate the help.

thanks

I use a Wiremold for extra outlets. No extra circuitry, no filtering, no surge protection. Recommended by Almarg.
I've been using a Zero Surge 8R15W-I for the past 7 years and find it to be non-intrusive with source components. It gives me a peace of mind, but I question whether it's necessary as I live in the SF Bay Area and lightening strikes are extremely uncommon. I plug my amp directly into the wall and haven't had any problems doing so.

The Zero Surge website has good information:

I really don’t think the Zero Surge is right for the Krell. I own a Brick Wall (same design) and the sonics of my 300wpc Sunfire amp suffered. Dynamics were affected and the amp sounded anemic.
These power conditioners use filtering which is excellent for lowering noise on low-current sources, but cant handle powerful amps.

Many manufacturers of these passive conditioners state that they are non-current limiting, but will limit the dynamics of high powered amps.

Look at Tripp Lite power strips.
