At the meeting of the LRS on 23rd November 2016 Malcolm Hamilton GM3TAL talked about 'Valves, Tubes and Bottles'. and invited members to tell of their own favourite valves. 

The development of the thermionic valve drove the advance of radio and electronics in the last century. Despite the stunning achievements of silicon device technology, valves are still the preferred solution for some challenging applications in amateur and professional radio systems, especially in transmitters.

A selection of the valves brought by members.
