    I am building a dc power supply and have a few questions about perfboards and connectors.

    1) For a transformer is it best to solder the wires to the primary and secondary lugs as I was using a mini female spade. Is there another connector better than the female spade?

    2) The perfboards I use have a very small diameter hole and copper around it and I physically can't put in some thick leaded components like power diodes and the FWB I am using. Is there a wider holed perfboard available or is there a certain connector I can use. I was thinking a terminal block but surely there is a better alternative.

    Eventually I will make an etched through hole pcb for it

    If it is going to be permanent system, I prefer to solder wires on to secondary terminals, although if already fitted with spade terminals you might as well use them, they are fine for contact purposes.
    I usually drill out slightly for large Guage connections.
    The small interlocking term blocks .2" spaced require a little enlarging of the normal perf board hole dia.
