Hi All,
After Arrarex definively disappeared, It seems the Arrarex "Little" was rescucitated for some months/years by Zerowatt that was selling this model late 1978.
This machine presents a classical Arrarex design: open boiler, "hollow piston", dry heating element (attached to boiler but separated from water by inox encasing), and thermostat (not adjustable, though).
Cheers,
F
