The HEATHKIT Model GP-11 Vibrator Power Supply is a compact, dependable, low-cost source of B+ voltage, intended for use with equipment requiring up to 100 milliampères of B+ current. Many of the low-power Amateur and Citizens Band transceivers fall into this category. It can be operated from either a 6-volt or 12- volt DC power source, such as a storage battery. Because of its small physical size, the Power Supply is ideal for limited-space installations in cars, trucks, boats, etc. Since the Power Supply can be switched on and off remotely, it may be mounted at some convenient location away from the equipment to which it supplies B+ voltage.
