Lots of discussions on these type of electronic transformers as a good alternative to the much more expensive to implement regulators upon first listening they made the music sound muffled, then in about 20 mins it all came together somehow, now from these initial experiments I can clearly see why anyone would go this way, these things are small! very easy to implement (cheap) and make the music sound good
some things I do not like I can clearly hear this unit oscillate at 37kc! so i will need to put it back into its enclosure, Yes I have bat hearing the other thing I dont like is there is no ramping up its voltage it all comes on the instant you plug it in, so no slow or soft start maybe add a mov? I am reluctant to say that these are as good as rod's regulators but they are prob good enough more testing on proper speakers will tell more of the story, my large fulton speakers will play way out hi 80kc!, so if there is something I am missing with my little fulton speakers these will tell the story. I am familiar with real musical instruments so here is What I listen for:
p.s. a few Thanks go out to defbykhorns and RayP Thanks for all your help. |

An electronic scale. Likely generates significant audible amounts of 37 kHz... |
