Astron RS-10A Power Supply 7.5amp input 115V 60HZ. - I have had this tank for many years. Still working great. Has significant wear and tear, scratches and dust. Recently upgraded and don’t need this unit anymore. Perfect for a small to medium power CB radio, or smaller HAM radio up to 25 watts or so. Still puts out good clean power. Sold AS IS with no warranty or guarantee. Thanks for looking :)
