    Transformer Hahn 230V 20v 6va

    Hello all.

    Not very familiar with transformers and did not find the datasheet for this one.


    Would these resistance values from Pimary and secondary normal? (check photo in red)
    Maybe someone with more experience can help me here
    Appreciate

    reasonable/possible but doesn't tell the whole story. Why do you think this is good or bad?

      What is the issue with this transformer dose it run hot when under a load what is the current or is really high or low according to what it says on the transformer if so please show how this transformer is being used

      One note I have seen a few of these open up in the primary side for what ever reason I have yet to see one that the secondary side open up

        Is it possible for transformer substitution?
        by mikey5791
        Hi all,
        Got this local made DC power supply (12/14V) given free as the transformer has melted. There is no marking or indication to identify what type or rating of transformer used.
        Fyi,. I had a busted autogate mainboard with transformer with marking 13-0-13 . Is this the 13v dc type transformer?
        My questions are
        1. How do i test to see if the transformer is in good working condition?
        2. Can this transformer (marking 13-0-13) be used to replace the melted transformer on the DC power supply?
        Hope you guys understand what i was asking. My intention is...

        Tektronix 422 with No Power
        by KYBOSH
        Picked up a Tektronix type 422 oscilloscope locally for a few bucks last year.
        It wouldnt power on at all so I stowed it away under my bench for later testing.
        Today I remembered it was down there and pulled it out to see what was what.

        I checked for continuity and everything checked out.
        There was a burned smell and a resistor was replaced with a temporary replacement (see yellow box in picture).
        The burned smell is very pungent/acidic and I am not familiar with these vintage electronics to know whether I am smelling the remains of the replaced resistor or...
