Rod Hogg contacted us about his Fansteel Balkite B-180 power supply after seeing the Fansteel ad in our July 2009 Do You Remember column. The unit weighs 27 pounds and consumes 27W. One pound per watt just to supply B power of 180V at 55mA. A batteries and C cells were also needed. Rod picked up the Fansteel more than 20 years ago but has never fired it up. One interesting detail he notes is they did not use a vacuum tube rectifier, copper oxide or selenium rectifier. In all his studies on electronics (more than 50 years!) he has never come across the electrolytic rectifier.
