Andreaea,
I knew this because i bought a pico 120w and circuit boards and parts to build two amb labs sigma 11 power supplies for my audio computer, but never have used them. maybe this will motivate me to restart that project as well.
i do have the linear psu for the stx, and use shunyata power cords and also use a shunyata v-ray for my power conditioning.
have a wonderful weekend!
Mark
