Nope, it’s not a cold solder joint. I’ve been a professional touring musician since 1979 and have done more than my share of repairs. As you can read above I will be picking up the original ps from my buddy. If I plug it in and it stays connected we have a plug size issue. I don’t know why Singular Sound doesn’t sell a replacement power supply. On the road I’ve always had back ups.
thanks for your input,
Doc
