Line isolated, “Universal” A-B-C Battery Eliminator / Power Supply for powering most vintage battery operated or farm tube radios. Front panel adjustable “A” (filament) Supply: 1.5. 9.0V with soft start – 2.0 Amp. “B” (plate) Supplies: +135V- 80mA, 90V – 60mA, 67.5V – 40mA, 45/22.5V – 5mA. “C” (grid) Supplies: -4.5/-9/ 22.5V – 2mA (“C” voltages easily user modified). “B” isolated from “A” and “C” supplies. Two LED indicators: one indicates power supply is ON, the other indicates radio is also ON and drawing plate current. For use as a universal bench supply OR to provide a permanent power source for battery powered tube radios. Small size (6.5 x 4 x 2.75) and light weight 28 oz. AC in: 85 – 265V, 50/60 Hz (USA plug type A). Operating temperature 0-35 deg C. Thermal overload and short circuit protected. Quiet (no fan, buzz or 60 cycle hum). Uses AC line and DC output common mode EMI filters. Includes User Manual and nine conductor cable (see photo). 3 Amp “A”, 100mA “B”, up to 270V “B” (using series connected eliminators) and/ or other A 1.25 – 9V adj. See separate listing under “Battery Consolidator / Voltage Converter” for similar device allowing mobile operation, operation without access to AC power (single battery required) or as a battery eliminator (using available linear AC/DC converter).
