My 2046w buzzes when the track is energized. Whistles ok but it hums when button is not pressed.
If the scope is setup correctly, I see two instances of DC offset: (1) The "zero" point seems a little negative; and (2) The extra spike in the negative part of the wave form.The cheapest lionel transformer has the same signature as the most expensive mth. Its not the transformer.
It was closer to $3850.00, but that was 1975! Not worth that now. Tools are only as good as the person who uses them.:smokin:Thats a pic of my $4k tektronix storage scope. I put on my mth supply and it was identical. Same as lionel power max plus and cw80. Did not check my zw but was able to find problem: loose copper washers on bottom of coil. Fixed!!
