Hi Clay: I concur with your comments re cheap connectors. I have had cheap connectors melt, short, go open and mechanically come apart. Fortunately these were in the days of big old tube-based robust rigs. I gave up on bargain connectors about 35 years ago. I’m happy to pay substantially

I have a ~30-year old Astron 13.8 VDC 20-amp supply that I got when it was retired from a project at work. I used it for low current applications for a few years, then it went to storage for about 5 years. One of the two power transistors failed a few months ago and this took out some other
