OUR VERY OWN DESIGN OFFERING - Vacuum Tube Battery Eliminator Power Supply Kit , for use with most antique radio receiver sets. NEW REVISION 2. This kit revision offers a major, and several minor improvements to our popular design! The PC board has been enlarged, to accommodate the power transformer. The transformer mounts directly to the board. This GREATLY eases assembly, AND creates a standalone unit. The unit can be mounted into a radio enclosure, or other enclosure of your choice! DOZENS and DOZENS sold! See our other listings, for a semi-built kit. NOTE: The case is available in gray and black, please message us with your preference. Below are some unsolicited feedback from buyers. Professional grade kit. Quality components and design.Highly recommended. +++++. Fast! Fine battery eliminator design! Seller goes the extra mile to be sure item is just as expected. Quality components! Thanks! Excellent once again (my second). Entire purchase process was GREAT!! I would buy again from this seller without hesitation! Communications was OUTSTANDING!! This is the second kit I have bought from this seller and again I am very impressed! It arrived quickly, was easy to assemble and the directions were on point. For such a flexible unit the price is a steal. A professionally built battery eliminator supply will cost at least 2 to 300 dollars more. The cool part is that you can build it yourself and learn something. Safety is advertised all over the instructions and even on the circuit board as well as the ebay description. Thank you!!!!! ---------------------------------------------------------------------------------------------------- This kit features three, independent DC power sources, to provide B+ (high voltage), A+ (filament voltage) and C- (grid voltage), for vacuum tube radios and other electronic equipment. For 120 VAC input voltages only. Complete kit with case, power transformer and line cord. The kit provides the following voltages and currents. All outputs are fuse protected. B+ circuit consists of a standard series string of twelve zener diodes. Twelve diodes allow more taps, and reduces component heating.
