Ok, now where did I put that flame proof jacket?
Let me start by saying I am not a technical bod but I do have a gift (or a curse), which is a critical ear. I don't know if it is a thing learned over time or just the fact that I have a highly perseptive sense. Either way it's there.
I was once told that if it sounds good to you then it's good. Even if on paper (spec sheets) it shouldn't. Now with that covered and all you test geeks at the ready with your Multi Meters & Flame Throwers
here are some pics of some Class A and some OBCA (Output Bypassed + Class A) AD744's.
Obviously there are neater ways of doing this especially if you are using SOIC on Brown Dogs. HiFlight (Ron Kerlin) makes and sells the nice neat modules and is far more qualified to comment on the pros and cons of using them.
Just for reference I have only ever used these in my P3 and P3+ so can't tell you how they fair in different circuits or amps.
