DTK power supply fixed my hum/noise problem

  • Hi Sparkers,

    I just received this grounded power supply from Amazon Sweden (https://www.amazon.se/dp/B07VTSF5F8?ref_=pe_20773151_507143461_E_301_dt_1) which appears to have fixed the significant hum/noise problem that the original power supply caused. The original one was delivered to me by Positive Grid despite my upfront warning and their promise to send the amp with a grounded cable.

    On the upside: I ordered the amp on November 22, and it arrived in Sweden on December 15, and it came together with the included carrying bag.

    Hopefully this will help others with similar hum/noise problems.


  • Copy that!

    I too got a DTK power supply to ground the hum. Works perfect!
    I got mine from Amazon.de - here's the link: https://www.amazon.de/gp/product/B01HWT7NKG/ref=ppx_yo_dt_b_asin_title_o00_s01?ie=UTF8&psc=1

    PositiveGrid did send me a replacement power supply too, but I didn't have the nerve to wait and risk my having my Christmas jamming ruined by humming, so I pulled the DTK trigger on Amazon for a sure shot...

  • I contacted PG several weeks ago to request a grounded PS based upon the various posts from other users.
    As the replacement had not yet arrived I decided yesterday to purchase a DTK PS from Amazon UK. It arrived today and has solved the excessive ‘hum’ issues. The annoying noise has been eliminated.
    Shame on PG for not acting upon feedback and supplying grounded PS with all new orders of the amp.
