VALVES NOT ON THIS LIST MAY BE OF INTEREST SO PLEASE SEND A LIST OF ALL YOUR VALVES.
However, domestic radio and domestic TV types 1950-1980 are usually of no value as we probably have a lifetime's supply of these valves already.

 

Please note: These prices refer to unused West European, UK or USA valves in clean condition and original boxes. If the valves have black stains, used appearance, missing print, are without their original box or are manufactured in China or East Europe, they have a far lower resale value.  Approx. 10% will be deducted from new valves lacking individual boxes. Please state clearly the condition of the valves on offer as we do not wish to cause offence or disappointment through misunderstanding.
