The Coherent Complementary Feedback Pair

[Stee]

Reamed after a prolific inventor by the name of George C. Sziklai.

In essence, a high gain super transistor, somewhat similar to a CFP. But there are major difference feature is a coherent local feedback.

Why is the coherent local feedback?
Basically, more difficult to design local feedback is the bias circuit
That circut generate a difference between two rails,
then a distortion.

Using two diode for fixed bias of drivers:
signal in just one, NFB just one, so coherent.

Thermal drift is compensate by two NTC resistors on each
final transistor's case.

It is easy to break out into high frequency oscillations with two capacitors or a little coil between drivers and finals BJT.

Performance like a live concert without distortion.

You should go into marketing.

same concept
but with a partitor between NFB
so a voltage gain
for example 5R6 and 24R in output stage
