STK4036X to 4042X1 typical application circuit

Rl l is the common emitter resistor of the output transistors VTll and VT13 .
It is different from the common emitter resistor for each tube. This is Sanyo's
unique approach. o
    1 The output part of the 8-pin packaged ST K4046Xl and 4048Xi
is due to A dual-tube parallel output is used, and its output connection method still adopts the conventional method
, that is, each tube emitter is connected to a resistor to balance the working
point of the tube.
