    On farnell website I just can't find the voltages I need in the suggested 15VA...

    So options are these 2 TXs.

    Any good?

    The other solution I read somewhere else is to find a single transformer with different voltage on each secondary windings... Probably not an easy find though...

    Yes no problem Francois, sorry I missed this thread before now.

    I was only saying that you could use lower power trannies as you are proposing to use two for each voltage. 30VA (1st tx) + 30VA (2nd tx) = 60VA power rating.

    Using larger rated trannies is perfectly OK

    I love Hendrix for so many reasons. He was so much more than just a blues guitarist - he played damn well any kind of guitar he wanted. In fact I'm not sure if he even played the guitar - he played music. - Stevie Ray Vaughan

    im trying to work out the same thing so there are 2 thicko's in the class
    as i understand it i need 2 transformers 1 with a secondary output of 80v and 1 with 60v.
    the website states,'The 30VA (2 x 15VA) types in the Mk2/kit version' . so i think this means 1 transformer with a primary of 15va,secondary 80v and 1 15va.secondary 60v.??

    also how important is the primary value as the production norton psu uses 1 giant transformer rated at 1000VA

    my head hurts!!
