Line isolated, “Universal” A-B-C Battery Eliminator / Power Supply for powering most vintage battery operated or farm tube radios. Selectable “A” (filament) Supply: “A6″ (6.0 -6.5V) or “Ax” (1.25-5.0V)- 2.5 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” supply capability can be increased 20mA by reducing “A” current from 2.5A and/or by reducing ambient temperature to 25oC (from 35oC). “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.

Serial number will differ from that shown in photos. Search separate listing under “Battery Consolidator / Voltage Converter” for item allowing mobile operation (single battery required) or as a battery eliminator (using available linear AC/DC converter) for many vintage tube radios.

This unusual amp unit features battery operation with AC and DC power cords on the back. It appears that the large mechanism toward the rear of the chassis inside is a generator (Genemotor switch on the faceplate), perhaps the generator is to recharge an external battery (not included).
