Hi..Made a similar circuit to the image : Inputs were not grounded...I used collector resistors at first so could position Vout dc (1/2 of supply) but after adding wilson mirror at the top : ...... big R : clip at top since Vout is close to V- (yh?)
Yellow = difference signal purple = common signal(was about 100mv)
How to fix this?
Also https://forum.allaboutcircuits.com/threads/high-gain-from-a-bjt-ce-amp-with-no-bypass-cap.117823/
what's the function of q3 and q4 (5th to last post on page 1)...Thanks
