Hi. I´m building the ross compressor from this layout http://www.aronnelson.com/gallery/main.php/v/Toneys-Album/Rossv4.jpg.html

I´m a little confused about the toggle switch. I know I´m suppossed to solder the 39 k resistor to lugs 1 and 3 (the outer lugs). But wich lugs are to be connected to the board points (swP & sw)?
Thanks

One end of the 39K resistor across the switch goes to point Sw (doesn't matter which end, you can position the switch however you prefer when it's mounted in the enclosure). The common pole of the switch (the contact that the switch moves between the lugs) goes to point SwP (where R1(150K) and R3(10K) are joined). If you're using a standard on/off/on switch as specified, then this should be the centre lug.
Bringing you yesterday's technology tomorrow.
