pure5152Picked one up, I've been trying to mod a couple of the first runs...but they are a M'f to desolder and fix properly...but a simple shield mod is relatively easy and cheap to do.
DarthpoolI got a replacement & if the power source is good you won't need to add shielding. The Russian on SBAF was joking about how his business picked up after all the Russian owners of NBM started reading SBAF complaints of the humming. He also mentions that the manufacturer is adding shielding. All I know is I don't hear a hum on my replacement.
