[AMRadio] Apache AM mode alignment steps ??

I've been following the Apache thread with great interest because it is a favorite transmitter of mine.  Can anyone list a cheat sheet that I could put in my manual and then use in adjusting the audio properly with my oscilloscope and audio generator ?  Is a simple audio sine wave in the voice frequency range sufficient?  Would you sample high or low ?  I once built (and may build again) a little 5 or 6 tube speech compressor out of a 60's QST and remember that it worked extraordinarily well with the SB10 and later with my Marauder.  I don't remember using it on AM much because the move at the time was to suppressed carrier operation.  Now that I use the Apache once again and really enjoying the AM envelope, am I correct in assuming that adjusted to a sort of alignment procedure on the bench, any problems I might have would be relative to the speech passband or my mic alone?

Thanks in advance for any comments.
