Rhysh,

Any comments on why Jeff Rowland engineers decided to use the inverted arangement for the construction of this amplifier.
What is the preferred method of adjusting the bias? Do the remaining two chips need to be out of the circuit as you adjust the one.

I wish those folks would PAY so we can begin to play. This time around the project will be a work of art. Much learned along the way. More yet to learn.

I couldnt tell you, you are better off looking for more information from alex88.

All three chips are in the circuit whilst making ajustments, this is the way which it seems to be done.
