MFJ-4225MV MFJ4225MV MFJ Original 25A Switching Power Supply

Works great the first 5 years, then mine blew-up- not repairable. Other than that, it worked quite well. Only issue than the meltdown was that if you had stray RF in the shack, it would affect the supply. For example, even a portable driving a small magnetic mobile antenna near the power supply would totally shut it down. The fan is very noisy, but did its job. Great fun while it lasted.

Great high quality, clean 12V power supply in a small package

Works well, but fans are very loud. Had to hide it in a cabinet and can still hear it in there.
