Ultrasonic Oscillation


Hi. I have had recent issues with my Snell Ds, tweeters not working. Anyway this led me to test of all of my equipment including my GMA Europas. Their tweets were dead also. I dropped an email to Roy at GMA and he suggested that I may consider the possibility of ultrasonic oscillation in either my amp or pre-amp. They are the Odyssey Candela pre amp, and Stratos amp. Could you please explain what it is, and more importantly what are the causes. Soon I'll get a diagnostic locally and sending the pieces to Klaus for repairs if needed. I look forward to your insights. Thanks much, Dave

Not sure why I read this old thread but I did. A very interesting read, and now I'm curious as to how the situation resolved. ???
Yeah, we ought to have an unsolved mysteries category, it would be interested to see what the outcome turned out to be. I liked the one with the system hum that baffled the OP for quite a while and was finally traced/linked to the dc cabinet lights in the kitchen being on.
Hello all, I was going through some threads discussing palladium and came across an old thread of mine. So Timru here's the rest of the story and no it wasn't the kitchen lights although I only wish. As part of my desperation and frustration I dragged all of my equipment to Music Technology and Bill Thalman's gave it all a clean bill of health. I called him back to discuss and he came to my house to listen and said the high freqs were performing as they should. So now what to do, listen to my wife who said the problem had to be me. Many times. I had my hearing checked and now with hearing aids music is beautiful. I now consider the ear horns as one more critical piece of equipment in my system. Am I hearing what others may hear, most likely not but in my limited ranges a great joy.
And that's the rest of the story. Regards, Dave
