[Elecraft] k2 low audio on SSB

[Hank Kryger]

Hi to the group
I am constructing a K2, 5669 and just installed the KSB2 mod.  All 
alignment tests for the K2 and the KSB2 where as noted in the manuals.  
I have however one cause for concern.

The Audio is low.  I have to turn the AF gain to fully clockwise to 
hear stations.  Before I installed the mod I could hear most stations 
with AF at 12 o'clock.  With the SSB mod the stations come in extremely 
clear with very good audio but low audio strength.

Any ideas as to what the check or look for.   thanks 73's Hank
