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

[N6MQL]

Wayne,

The following supply meets your requirements almost to the Tee. There 
are 3 to choose from. I have tested and used the second one in 
Professional broadcast & off-line Video production as well as Audio 
recording.  I have not heard noise from them that would cause an issue.  
Furthermore, I have used these with my KX1 and the K3 when having fun on 
vacation. Specs can be found at http://us.tdk-lambda.com

Lambda - LS25-12 (LS35-12) - $16.50 ($18.25) Newark electronics - 3.1" X 
5.0" X 1.1" (3.9" X 3.2" X 1.4") - 10.8V-13.2V @ 2.1A (3.0A)

Lambda - HWS30-12/A - $54 Newark electronics - 1.24" X 3.23" X 3.74"  
9.6V - 14.4V @ 2.5A

Now, if you really want to go crazy with this! (and I know some of you 
out there will)

Lambda - PFE300S-12 - $250.00 Newark electronics  - 2.4" X 0.5" X 4.6"  
9.6V - 14.4V @ 25A (YES 25A !)

Have fun, and enjoy your holidays
