    They looked like Step up Xmers. Guess I got fooled.

    Not really fooled as they do look like step up transformers but the giveaway is the xtal freq labeling and if that was missing I would of went with step up transformer also.

    If you have no use for them at all, you can probably open them, empty them, and convert it into a nice plug-in solid state rectifier.

    I picked up a bunch of them when I picked up a lot of tubes. I paid 4 bucks a pop for around 20 of them I guess in the grand scheme of thing. lol. @gadget73 I like your Idea of converting them into Solid State Rectifier.:thumbsup:

    These are not transformers, they are elements for a Nems-Clark Wattmeter.
