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.
