Here you find the datasheet of the STK0039 and the internal circuitry.

Thanks
Hi Billlion Power!
Yes ...your modification will work!
You must take care of the thermal tracking of the output transistors and put a pot for adjusting the bias...i prefer to use a transistor as VBE for traking, but the diodes can work if you put them in thermal contact with the output transistors.
So ...turn on your soldering iron...
PS:Maybe the compensation need some fine tuning......
Yes!!! ..It's allways a good design pratice to put a capacitor across the biasing network!Duo said:Wouldn't it be even more effective to put the cap across the whol diode network?(right from base to base?)
I'm not perfetly sure on this one, but I've done and seen it before with good results. Any opinions?
