Today I have made a RC phase shift oscillator producing 90KHz of sine wave with a 6V dc offset.Now I want to amplify its current upto 100mA amplifying the overall power of the signal, I have tried amplifying using 2n3904 and as well as 2n6292 but none of them worked I hardly got 14mA max using those,first I tried without using any base resistance(fig1) then I added one 3.3K resistor to the base(fig2),detailed schematics of the circuit is attached below please someone help me fix it or suggest me a better idea of doing this,thank you
