I’ve been looking into the Mullard company (the main/biggest factory was in Blackburn - Lancashire) due to them being one of the biggest valve manufacturers in the UK (there are some brilliant videos on YouTube of the manufacturing process (lots of click clacking machines 8)) in the factory by the w...

Re: Thermionic Valves

On a slightly related note I have one of these for my iPod dock:- 408E84DE-9711-4992-B204-944514609345.jpeg I enjoy watching the valves warm up and glow and the one at the back changing based on the music going through it. The more recent version of mine is shown in Martin’s link by the looks of it...
