As announced last week Tony Voorveld ZS6CCD will be delivering the keynote address at the upcoming "Radio Technology in Action, entitled "The Magic Lamps". The lecture is accompanied by demonstrations depicting the evolution of the valve from the early experiments by
Thomas Edison (the Edison effect) to the development of the diode, triode and x-ray tube, thus opening the door to the modern electronics industry.
As all with previous lectures by Tony, this one promises to be full of action and interesting demonstrations.
