Well, whatever did you think, shame on you......... You know, it is said that there is nothing new in show business or advertising and here we have three photos just to prove this point. Here we see Petula Clark in October 1950 at the Castle Bromwich Radio Show somewhat agog at the size of this 5 foot Mullard valve model: -   And this 'ad opportunity' was again exploited  with a young lady from  Chorley Wood College for Girls with Little or No Sight examining the same giant valve model at the London Science Museum in November 1950: - But this wasn't a novel approach at...

 We bring you our latest exciting new development. Some of you will be aware that post manufacturing treatments of valves is currently en-vogue. I have read with interest just how beneficial cryogenic or ‘cryo’ treatment of valves is purported to be. Allegedly, the stresses induced during valve manufacture affect electrode structure tolerances within the valve and cryogenic freezing relaxes these – permanently. As a scientist, I understand that many of the metals used in valve manufacture such as Copper, Molybdenum , Nickel and Tungsten are transition metals. I am however, unsure how a transition metal’s ‘electron ship in a cation...

 'What are the Wild Waves' saying was such a catchy little phrase, everyone was jumping on the bandwagon after Igranic's clever dodge,  here you can see a 1922 advert by British Central Electrical whose similar take is "What are the Air Waves Saying.

As you can see, a rapid reduction in temperature causes the valve to reach for it's scarf and additionally makes it very grouchy so that when it grabs the electrons that comprise the signal it amplifies, it does so in a very rough and unkind...
