As some of you may know, one of my other passions alongside Pinball, shooting (Not animals!) and Drone flying is Old TV and Radio equipment. Not something that I'm fully conversant in yet, however as part of a slow learning curve I'm getting there with the old Triodes/Pentodes etc etc.
The vacuum tube (or thermionic valve) is probably the one of the greatest inventions of the 20th century. It heralded the beginning of the information age, an event as significant as the invention of the steam engine that brought humankind into the industrial age (with all its benefits and pitfalls). It made possible for the first time the amplification of electrical signals, which is the foundation for telecommunications, mass entertainment and information technology.
I'm always on the look out for NOS and used Valves - They arent worth much nowadays, however always interest me and I am always keeping my eyes open for them.
Please - if you have any kicking about that you dont want, or you have an older relation that used to do this sort of thing and has drawer after drawer of these... please let me know!!
