This sounds interesting. What's an NTC? Looking around the web it looks like there are lots of places in Holland which sell devices for making machines quieter. Here in the wild west it looks like everybody sells the same generic power supply and any attempts to obtain information about quieter ones are typically met with an incredulous stare. This is probably because in America people believe that if something makes a lot of noise, then it must be really powerful and hence good. Maybe you can recommend a vendor of the above-mentioned kits (or whatever silencing solution you currently use). Ideally one which will ship to Canada, although I have some friends in Holland who could forward the goods if need be. -chris
