[Elecraft] Looking for miniature 14-V power supply for travel, use

[Larry Phipps]

Look through your old laptop PC power supplies. They are typically 14-19 
VDC with 1.5-2.2 A current supply capability. Some are clean, some are 
dirty, but they are generally quite small. I used to use one with my K2 
at trade shows.
