Can't go wrong with Astron!
Good power supply, only the posts in the back are different than in the picture

Works great for audio equipment
Bought this to power some audio equipment and bypass the stock switching power supply. Provides all the juice needed and improves the sound. Altering the voltage using the adjustable trim pot was easily done. A great inexpensive alternative to the audiophile linear power supplies being sold out there.

Precise and quiet
I bought one of these 2nd hand but wanted to leave a review here. This is a good supply for probably about a 40 watt radio by itself, though your manual will tell you what size you need. This old 2nd hand one still puts out a perfect 13.8 volts and is nearly dead silent. I must have my ear close to hear it. Im actually using this with a 100 watt radio. I run the power to a 35 amp hour AGM battery and then over to the radio. It keeps up no problem. The battery buffers the extra watts I need for transmitting and will keep running for hours if the power goes out. If I run the battery down I use a regular automotive trickle charger to get it full before using the power supply on it again. Super smooth unit. About the only downside is it's bulky compared to a switching power supply.
