A home made passive pre amp using 50K Alps blue potentiometer in a solid cast aluminium box. I have painted it using black Hammerite paint. It is ideal between a CD player and a power amp, especially an old Leak or Quad valve amp or any modern transistor amp. Asking 20 pounds plus 5 pounds postage within UK.
