    Theory : uh was it like ....
    (25+25)*sqrt 2 / 230v*235v?? = 72,2 volts
    (24+24)*sqrt 2 / 230v*235v?? = 69.4 volts
    Goal : 68volts DC

    Well, rectifier steals maybe 1 volt (Vf =1.1 volt) ?

    Can you please confirm? 24+24 is harder to find.
    Ok I am not a math person but I think you might be doing this the wrong way.

    25-25 = 50 x 1.414 = 70.07 - rectifier 2 x 1.1 v = 68.5v

    Single or double primary no difference, dual primary are easier to find. You won't have any trouble with 25-25 or 24-24 v sec.

    Don't forget you are measuring V without load. You also said you have a 25Mtr run

    Sorry about the links the forum shortened them.
