I built one of these. Determine your resistor before soldering.
I have LED's from the early 70's to current production and
this little bugger is handy dandy. I plan to use it for my Aleph J
boards to set the brightness of the blue LED's. Sorry if I went off topic.

if you see (irrelevant of size/power) same type of OS parts, due to Square Law arrangement, count it done
if you see dissimilar type of OS parts, not so - even if from experience I know that my funniest amps are surprisingly good even if illogically mated with some speakers
if you see present NFB, means DF is better, so that counts
if you don't see overal NFB (as is case with amps having autoformer gain), not so, but - again - Square Law means something
in short
- some of my amps (upper criteria) doesn't care what load is
-other my amps care, but not so much as it is usually expected
observation - speakers having that sort of impedance module really not belong in A Class Fairy-tale
explanation - having A Class amplification naturally calls for speakers of greater efficiency but even more important - greater sensitivity; food for thoughts/illustration - which one is better for your home - 15" bass driver of 93db/W/m and 350W, or 15" bass driver of 93db/W/m and 80W?
leave those from graph for well informed HiFi Aficionados..... not knowing better

Thanks for bringing light into darknessif you see (irrelevant of size/power) same type of OS parts, due to Square Law arrangement, count it done
