Hi,
I've built this oscillator from **broken link removed**.
The oscillator stage works great, it looks like an almost perfect sine wave except for the peak of the negative part of the wave is slightly flattened.
The emitter follower section however extremely clips the negative half of the wave. Is this because the bias point is too high? I take it this stage is getting a bias from a DC voltage from collector of 1st transistor, how do I work out what it is and what I should change it too? Or could I put a capacitor in between and another resistor from supply to base?
Any help in understanding this circuit would be greatly appreciated.
Thanks,
Mick.
