Those mini radiotubes you spoke of Parasuraman, existed already in the sixties of the previous century.
Todays silicon chips are made on Wafers that are produced on Worldfamous ASML machines from The Netherlands (Eindhoven). However very likely in the next years those chips will be replaced by optical chips that are not only much faster but also much more energy efficient. By a new Dutch firm that started like ASML but is to be the next new evolutionary step in electronics that is said going to make those future optical based chips for our next smartphones, laptop computer and possibly other portable devices soon!

That's precisely why it's bad - you don't want a dielectric (insulator) added to your potentiometer tracks!

Iñve been using WD-40 for many years with great results. This product has dielectric features.

Not sure if that was a question, but from what I was told is that the reason for tube finals in transmitters is that they can withstand lightning strikes better than transistor finals. This is particularly true in the American Southwest, not sure about other areas of the world. FWIW

Vacuum is going to come back as miniature and microscopic tubes to be used in computer, because of its advantages. Many of its advantages were compromised when the world switched over to Discreet components. That's why the Transmitting is still using the Valves. Many professional studios use Tube Preamp, Tube Microphone and many such other devices, because of its quality reproduction. Many thanks for your comments!
