Hi all. I have toroid trans (230v in) with TWO RED wires which label indicates as " IN 230v ...RED-RED " ; then it has " OUT 2x 20v ...BLACK-WHITE " referring to TWO WHITE and just ONE BLACK.
I was advised to NOT CONNECT THE BLACK TO ANYTHING AT ALL....Just to connect the two whites to the pos and neg terminals on the phono preamp board's input.. After several months of trying to eliminate the HUM problems I put it all away ! Now I am going to try yet again to sort this out.
If you have ANY thoughts at all which may help me out I'd be eternally grateful.
Cheers :)
