PS Audio Noise Harvester Light Not Blinking

So I have 5 PS Audio Noise Harvesters. I noticed that 2 are not blinking. When I take a known blinking Noise Harvester and plug it in an outlet with a non blinking Noise Harvester it starts to do its thing and blink.

Does this mean the 2 Noise Harvesters are not working or is it a bad LED?

Two of my original five Noise Harvesters have died over the years. One partially melted while in the socket. If you suspect one isn’t working or is behaving oddly, get rid of it.

Thanks PB. I’m wondering if there is a warranty?

Our products are warranted for 3 years from date of purchase. We’d be happy to replace the Harvester for you if you’re in the US. If outside you’ll have to speak to your dealer.

Thanks Paul…unfortunately I have them over 3 years.

Did you ever hear any difference with them?

I absolutely hear a difference. I live in NYC and the blue light would blink very often at times.

I had all 5 Harvesters plugged in various outlets in my listening room. Even with only 3 working the noise floor was lower creating more detail and separation.


Contact our service department and ask for Jeremy. Tell him I said it’s ok to replace the broken ones for free despite they are out of warranty.


Thanks so much Paul. That’s very generous of you! I appreciate the outstanding customer service.


Hi Paul,

I seem to be having the same issue. Got it about four years ago but hardly used them. Recently, when I plugged them in various different wall sockets and Dectet, the led didn’t blink at all.

Kevin suggested to send to your local distributor here in Malaysia and the distributor’s prognosis is that the Noise Harvester is unrepairable.

Is there anything that can be done?

Unfortunately they cannot be repaired. We typically replace them.

I bought two of them from Music Direct. Both had no light blinky. Sent them back and they sent me two new ones toot sweet. The new ones blinky like crazy. Especially when plugged into the back of my P20, which seemed counter intuitive.

Greetings from Hong Kong! I bought five Noise Harvesters in 2018-Mar (all plugged into the duplexes of my two P20s), and two have already gone kaput. Can I get them replaced at Radar Audio?
