PS Audio Humbuster III

I bought this to test if it would work in getting rid of my transformer hum problem. It did, and I bought parts to build my own "Humbuster" so I don't need this anymore. I literally used this for about 25 hours. I will sell it for what I bought it for which was a very good price. It comes with the original power cord, manual and packaging. Except for the manual (which was folded by the original owner) it's in like new condition and you will not be dissapointed with it. $150.00 shipped CONUS is the price. Very good deal on this.

My response is: If you need 60 seconds to respond in one sentence, you probably should't be evaluating Polk speakers.....

No Fred, I am just using the schamtic you sent to me to make a "humbuster". That would be a good idea though to open one up and clone it. I just didn't want to do it when I wasn't going to be keeping this one.

Sorry, I don't have an "original" schematic for the Humbuster. I just have one that is an approximation of what is inside the Humbuster. You can find schematics on DIYAudio.com to make one.

OK kewl Greg.I thought may be you had purchased it after our exchange.Let me know how it works.No Fred, I am just using the schamtic you sent to me to make a "humbuster". That would be a good idea though to open one up and clone it. I just didn't want to do it when I wasn't going to be keeping this one.

I am curious to see how this works for me. I also have a transformer hum in my amp. Very low level, but it's there. I have tested the amp without the preamp connected and removed the ground pin from my PS Audio power cable to the amp. Same low level hum, I figure it's the transformer, we'll see.Carl

Carl, this will reduce/eliminate the transformer hum if it's caused by the DC on the AC circuit. However, depending on how much DC is present, you may (or may not) need another Humbuster. In the manual PS Audio recommends one Humbuster per peice of equipment. Of course, they are trying to sell Humbusters too. When I bought this, I was thinking I could plug this directly intot the wall and then plug my voltage regulator, Equi-Tech balanced audio conditioner, and all the pieces equipment that are connect to it. However, one Humbuster will not eliminate the hum in all of your transformers. I found that out as a fact. If you plug the Humbuster in between your power conditioner and amp, you should see a reduction or elimination of the hum in the transformer in your amp (assuming it's caused by DC on the AC line of course). Hope this helps Carl.

Since DC induced hum is a problem with toroidals these types of circuits will only be effective with them.

Thanks Greg and Fred! I am pretty sure the big Classe amp is the source of the hum. It's low level, but present. I do have a torodial transformer in my Rogue preamp. I will experiment and have some fun!

Is this still for sale? thx..makk010253

Your tweeters will be the first to let you know Carl.
If they are still active, then there is not a whole lot of DC in your AC.
Klipsch tweeters are notorious for letting you know how much DC you have in your system.:cheesygrin:
The PS products are great regardless.
Just an excellent company from top to bottom.
And you could not deal with a better Polkie than Headrott!:cheesygrin:Testing

Would one of these eliminate a buzz I have from my tweeters? I didn't have one when using my gfa7500 but now with the 5802 I can hear it from about 2 feet away.

Greetings Greg!
I received the Humbuster today in perfect condition. Thanks for packing the box so nice. The Humbuster did not help with my hum. The low level hum is present without any input from the preamp. I even disconnected the ICs and used a "cheater plug" to remove any potential ground loops. I need to look elsewhere inside the amp. It's not a serious problem. It's not audible until you are within about two or three feet of the speaker. I just know it's there and I am a little anal.
Thanks for the smooth transaction!
Regards,Carl -
Hello Carl! Are you going to sell the PS Audio humbuster due to the fact that it did not solve your hum issue? I would like to give it a try in my set up. Maybe it could solve my hum issue. Please let me know if it is for sale. Thanks!

This thread is a bit dated, but there is nothing in a Classe amp that will make it a source of hum. If anything, the amp would be susceptible to hum. Most of the legacy model Classe amps, starting with the CA-XX0 series have DC blocking circuitry ahead of the transformer, to eliminate most levels of power line DC. Earlier production models that did not come with the DC blocking circuitry could have it retrofitted on a small PC board. Possible sources of DC include but are not limited to devices that load the AC power line asymmetrically, such as light dimmers, halogen lights, and equipment with speed/level/temperature controls that employ a diode as a means of dropping voltage.Main System: Denon DP-59L | Audio-Technica AT33EV | Marantz SA-11S2 | Classe DR-10 | Classe CA-300 | Classe RC-1 | PSB Stratus Gold i's | DIY Balanced AC Power Conditioner | Acoustic Zen and NeoTech cables | Oyaide and Furutech power connectors | Dedicated 20A isolated ground line.
