Not sure when these came out, 1960’s – 1970’s (?), but an Eldon powerpack, presumably for a vintage slot car set. Untested, but hums to life when plugged in. Very fine condition – see images.  Model #3406, 14V output.  Buyer to pay $14.75 for shipping in the US.  Happy to insure or ship abroad but it costs a little more, please inquire.  I accept credit cards via PayPal - also personal checks, or cash in USD or Euros. See "view seller's other auctions" above to combine auctions and save on shipping. Thanks.
