yes i know, there are centain drops...
but whether it be square or sine, cross over distortion does occur, i checked with both waves on an oscilloscope...
thats why i went for the little bit of smoothing using the oldest OPAMP. it will convert square wave form into sine.. since 10 and 11 outputs of cd4047 produces 180degree out of phase wave froms, i get a really good sine and cosine from the OPAMPS.
so back again to how to overcome cross-over distortion, and make this a class AB amplifier. i know a diode drop at the setting transistors will do it, as is indicated in text books. but i am not getting any result when i do insert diodes..
what to do? because even though the present circuit works (with poor line regulation!), loads like energy saver and tube lights flicker at operation.
and if someone can tell me how to improve its voltage regulation, it would be so good of them.
