Reliable, old-school power for sensitive electronics. The 584D is a classic linear, non-regulated universal adapter. Unlike modern switching supplies, linear adapters are preferred by hobbyists and audiophiles for their simplicity and low electromagnetic interference (EMI) when powering vintage radios, small hobby projects, and low-drain devices.

Seems Decent

Lots of settings and attachments. Should be useful. Bought to replace a plug for a radio. The power supply is some new switching stuff that totally blocks AM. Since no batteries makes no sense! Supposedly a Biden mandate (no surprise).
