Here is a Challange
Just suppose the pnp transistor had not been perfected/produced . Could any of you design a Dc coupled amplifier using NPN devices only !!!
Target power is 30 watts rms or more in 8 ohms at less than 0.1 % distortion midband
I have produced a no of small class A designs with succes
You can use any technique multiple supplies etc any thing goes but no PNP devices.
It seems to me that most of the designs I have seen on this site are all generic and feel that the challange will stretch our minds a little further
