Acquired from a reliable source, a high end hobbyist private lab. No means to test. We are surplus equipment dealers and do not have the ability or knowledge to test equipment for functionality beyond plugging it in and describing what we observe as best we can. 2 You are purchasing used equipment – most is untested as stated in our description. Please reach out to us directly if there is a problem. We are quick to respond and resolve. Used items have a 30-day return. We have no knowledge of the history of the equipment. We do not have power cords to provide unless they are attached to the item or unless stated that they are provided. If one is pictured it is for testing purposes only unless it is attached or stated that it will be included. Our items do not come with manuals or any other accessories unless shown and/or stated that they are included.

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).

This came in from a ham radio estate, have no clue what this does or is for. Use zoom, I did not plug in, I would think you want to bring this up on a variac… Not sure if amp or power supply or? So untested, as found, no bottom panel. Please see all pictures and use zoom feature. Often the pictures describe the item better than words. Also please see the 11,000+ vintage radio related parts and other great antiques and oddities I listed. Old Radio’s are Fun and getting harder to find! Just like radio parts? Thank you for you order and please follow my store. ! New items added daily. Also you can go into my store and pick the category for easy shopping. Best to you and Many Thanks, Mike.

THIS COMES AS PICTURED AND UNTESTED. I BELIEVE IT IS A 2-CHANNEL POWER SUPPLY BUT THE PARTS IN IT ARE VERY NICE AND COULD BE USED IN AN AMPLIFIER BUILD.

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. 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 for neat connection to radio (see photo). 3 Amp “A”, 100mA “B”, up to 270V “B” (using series connected eliminators) and/ or other A 1.25 – 10V adj. 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.

Offered is a vintage homemade tube amplifier. Has some wear, see pictures. Please contact with any questions regarding item.
