The problem with RF (Radio Frequency) interference (severe AM radio buzz) started when I replaced the power supply and graphics card in my HP Pavilion desktop

Have four, and have made 5 friends happy by solving buzz, hum problems in their high end gear.

A very cheap solution to what could be an expensive problem for some.

Thank you for making a fine product for a reasonable price that really addresses the hum problem.

No published specifications on clamping voltage (for any leads, L-N-G), no published specs on total Jules of surge protection, no master off feature, no info whether it cuts power after surge protection is over

I also recommend the Furman M-8Dx power conditioner for a home theater.
