Hi everyone im facing problem with my Sziklai pair. Pls look at my attach file. in the schematic,there is a squarewave input which i replace in my circuit board with a 555 timer. then u can c from my schematic i giv an input of 12V to the transistor.
But the problem is when i fabricate it on a pcb. and when i on the power supply, the output only gives an output voltage of 2.5V. I already make sure that the input does give 12V when its not connected to the circuit. and i found out tat when i take out the 555timer from the pcb(its place on a socket) the output gives a 8V output
can anyone tell me why i cant get 12V at the output??and how to solve this? thanks for replying
