does any one kno how to make a homemade powersoak i cant find another used scholtz power soak i been lookin so i just wanted to ask if someone knew how to build a simple load box like my21 yr olsd scholts powersoak
i bought huge power resistotors and a six way selector but i am curious do i shunt one lead of the load power resistors to ground lug or in line with the hot signal ?
my scholtz power soak is a box preforated with millions of holes and a bunch of power resistors but i dont kno where the selector switch is hooked up because i havent had the nerve to take my old trusty scholtz powersoak apart

any one got ideas ?
please no sarcasm
