About

Analog design and magnetic fields ; Retired electrical engineer.

Early years were in Motorola R&D with high power VHF transmitters.

Spent most years designing Induction Heaters and associated products (up to 1 megawatt power supplies).

I do enjoy restoring old tube type radios and the cabinets.
