    Hi all!
    Does anyone have a schematic for a simple B Battery eliminator? I have a couple of old battery powered radios to restore and would like to eliminate the need for batteries.
    Thanks!

    I don’t have a schematic, but this transformer would be a good start. perhaps it can be found cheaper.

    Hi Joseph and others.

    I have attached a 81 page PDF of connection diagrams for connecting vintage battery radios, it is used with a ARBE-III universal Battery Eliminator which I use.

    Enjoy Bruce

    When using Bruce’s simple schematic, use a polarized plug with B- wired to the neutral side to avoid a live chassis.

    Hi All
    I just wanted to clarify, the schematic I posted was from the internet. I did not intend to take credit for it. I tried numerous times to upload the website with it on but to no avail. The schematic came form;

    Joseph,
    I have attached a very simple and inexpensive possible solution to your battery eliminator issue for the higher voltage. A couple of “D” cells will probably do for the filaments.
    It requires 3 HP printer power supplies. I have found numerous type and power ratings at a local thrift store for 3 to 4 dollars ( Canadian) each.
    They have 2 output voltages, 32 volts and 16 volts.
    You need the ones with a 2 wire line cord. The three wire ones have the 0 volt wire (A) connected to the AC ground pin on the supply.

    If you wire them as shown they will give you your high voltage. The diodes are optional and will lower your voltage slightly.
    I have used 4 of them in series (without the diodes) to power a 40 watt incandescent light bulb as a test without a problem

    Thanks to all. For some reason, I’m not being notified of my messages, so I have not checked the site since last weekend.
    I’ll work through all of the responses today!

    Hi Joe

    Following is a link to a site that has a simple schematic for a very simple B+ power supply.

    I have and use an ARBE-III Universal Battery Eliminator which is really handy and easy to use on old battery radios. Can’t say enough for it. There is an 81 page manual with wiring diagrams for hooking it up. Following is a link to the Battery Eliminator and I have also attached a PDF of the wiring diagrams.

    I use an ARBEIII universal Battery Eliminator that works on any of the battery radios I have come across and find that it is really works great. There is also a 81 page set of wiring diagrams which show all the hook ups for numerous battery radios. I tried to attach the PDF but the site would not accept it. Following is a link were one can obtain it.
