Just out of idle curiosity, why do valves have a reflective chrome (or other reflective) layer at the top on the inside? Is it to prevent heat dissipation out of the valve and keep it at working temperature? Not all valves have it- particularly the larger power valves but most smaller pre amp valves do.
