[TenTec] Testing Argosy final amp current

[John]

After considering  several different approaches, I concluded that 
cutting the red lead at about the center of the run was both the easiest 
to access and easiest to repair.  The deed is done.

With a dummy load on the Argosy ( nothing said to put a load on the 
output but it seemed logical at the time) I measured the current with 
the output set to high and drive set to 1.  At 1 and below, the current 
is about 60-80 ma.  The manual says the quiescent current should be 125 
ma with the gain set all the way clockwise. I see 150 ma with the gain 
set about at 2. With the gain at about 8 the current rose to close to 
800 ma.  The measurement is taken after putting the mode control at 
LOCK. Am I doing something incorrectly?  Does anybody have any thoughts 
or corrections to my measurement process?.  Given the difficult 
replacement of the finals, I am reluctant to just play.
