  1. Hi audioguru and thanks for your comments.
    Actually I just found out that the trafo is only 20va, it is a wall-wart type from a decoration. I'm still in an early stage of the construction, having made the pcb and mounted most of the R's. I had not given thougt to potential problem of exceeding the V specs on the opamps. Thanks for mentioning this.
    The purpose of this project is a small secondary bench psu, so even 0.5A is sufficient. (I have another 723 based capable of 2A)

    I am also thinking about using this circuit(modified) in a 7A psu, I have a nice homemade enclosure ready with almost everything except the regulator, it even has provision for 6 TO3's
    ..but first I want to see how this version works..
