Tipp, disconnect input and output from first transistor stage. Then monitor collector voltage and fine tune 100kohm resistor to have about 4.5V collector voltage operating point. This is by about 34.5kohm. Reduce the input voltage to 1mV and modify the seconde 100k to 34.5k. Rewire in and output and check output at seconde stage. Its about 3V peak-peak which is a nice allover gain of 3000 and a nice sinus output. Keep on designing
