Ralph, 

Longtime Lowfer Lurker. I viewed your on-line descriptions of the power supply project and want to thank you for an interesting, informative, and entertaining account of it. Well done and keep the reports coming. :)

It is my view as a long-time tinkerer and hands-on advocate that projects and descriptions such as this are our greatest asset in inspiring, attracting, and recruiting others (especially from new generations) to these fields of interest. Well done and keep the reports coming. :)

I am personally intrigued with this project having lifted and carried a very heavy RF power amplifier with a roughly 2kW linear power supply (ouch!). Perhaps there's a switcher in my future.

You note in your update that the two-section TV flyback transformers had too small cores to handle the power. Would it have been possible or practical to use the cores as pairs (for example, side-by-side) and pass the windings around both cores to increase the power handling? 

73,
Joseph
