    Ok, potentiometer tests good. Changed 2n3055 transitior and power shuts down when I turned power switch to on. Put old transistor back in still at 37 volts. Model 905-0064-1 power supply

    is there anything that i should check next. thanks for any help

        Is the adjustment knob now working? A schematic would help.
