Description

Astron RS-35A Classic Heavy duty 13.8 VDC Linear Regulated DC Power Supply

  This RS-35A is in excellent Condition with only a few very light marks and no bad scratches.

 If the shipping cost is less than quoted, (if you are close to Wisconsin) I will refund the difference.

The Astron RS-35A is a classic heavy-duty linear regulated DC power supply from Astron Corporation, still in current production and widely used in amateur radio, CB, and other 12-volt applications. It converts 115 VAC (105-125V input) to a stable 13.8 VDC output and is prized for its low RF noise (important for ham receivers/transmitters), solid build, and reliability compared to lighter switching supplies.
