I have to say, the unqualified (completely absurd and unfounded) criticism of a certain user's iron port idea has completely spoiled my enjoyment of this little amplifier.
If anyone has already dared to try this unusual amplifier, please do not forget the thermal coupling of the BJTs Q8 with Q5 and Q6 with Q7 - or sink all four into a common aluminum body. Q9 must find its own cooling option, stand alone.
