[Elecraft] MFJ 4103

[Ron W]

Hi Elecrafters,
Does any one have any info on the MFJ miniature psu type 4103?  Although it 
is a sealed unit I wish to adjust the output to keep my internal battery 
charged. The nominal output voltage is 13.8 and I wish to adjust to give 
14.2 as measured by the K2.  I think the unit could be carefully cut open 
and after adjustment sealed up again.  Before starting on this exercise I 
thought I would check with your collective wisdom.
