[Elecraft] AF1 - couple of questions

[David Wilburn]

I picked up the lexan cases for the AF1 and W1 from W8FGU.  Very nice, 
well made products by the way.  Questions;

1. - I am currently running the AF1 with a 9v battery, but I will be 
connecting it to 12v supply here in the shack.  I was going to leave 
the 9v battery installed, as it appears the diodes that are part of 
the circuit will protect it.  But wanted to confirm.  The case is 
clear, so I can also keep an eye on the battery, but I wanted the 
battery in, in case I wanted to operate away from the shack.

2. - I performed the circuit changes documented in the errata, and the 
AF1 works fine with headphones (stereo jacks), but it does not seem to 
work with any of my external speakers.  Did I loose that option when I 
made the changes in the errata?  They seemed to be required for it to 
work with headphones.
