In preparation for the 10th annual Energy Science & Technology Conference, high frequency illumination experiments have been carried out to great extent. The main power supply constructed for the first half of the demonstration is comprised of a single 833A power tube, configured in an Armstrong “C” class oscillator operating in CW mode. Only little is given in this post, for there will be more presented at the conference.

The finalizing of a triple 833A tube supply is underway – all tubes will be in parallel.
