The Defender 82-3950 is a great linear 12 VDC 500 mA power supply.
It is quiet, has virtually no ripple, and is very well regulated.
It has a 2.1mm /5.5mm coaxial plug (center positive).
We suggest you insert the power supply plug into the radio,
and then plug the power supply into the wall
This will preclude a power supply reset condition.
