Post Subject: Those mechanical line stabilizers…Posted by Romy the Cat on: 9/27/2012

You need to be very carefully with them as they might be anything. I very much doubt that we need any AC line dedicated stabilizers; even though I do feel that it is good to have more or less stable line. The mechanical line stabilizers might be a bit too sensitive. If you have a voltage spikes for a few does of person you do not want the unit to react to it immodestly. The AC regulation has to be very gentile and you do not want to yank voltage too much by switching the transformer turns. Also, the transformers that those units have are usually very bad for sound. I did use a number of manual stabilizers and they all were sub-acceptable. There is another twist. Most of the mechanical line stabilizers has common mode and differential filters that made not for the “injected” voltage but for full load. Most of those filters not good, I mean were not good for sound. I agree that the mechanical solution is very simple and elegant, this is basically taping the transformer but the valuable transformers that I used did not sound right. I still have a few of them in basement and I do not see any use of them outside of my testing lab.
