[Milsurplus] Dynamic Mics and powered speakers

[WA5CAB at cs.com]

This question came up on G503 but I can't seem to locate the post to get the 
TM number where I found the schematic of the AM-6747.  The short answer is 
yes, you can run one of the amplified speakers off of 12-14 VDC but there is if I 
recall (that's why I wanted to look at the schematic again) a fixed dropping 
resistor that needs to be either changed or strapped out.  If someone 
remembers what next-level set either of the units were officially used with, I could 
find the manual again that way I think.
