Hi Folks!
I am new to this forum and hoping someone can give me some insights.
I am building a TL494 based push pull circuit to be used in an inverter, but I am not even to the power stage yet.
Scoping the unloaded output of the push pull circuit (see attached screen shot), one can clearly see the erratic pattern.
I do not know where to look for the cause of this.
I have checked for cold solder joints, jiggled the components, tweaked the pots up and down, to no avail.
See circuit diagram and build layout pictures.
Any debugging and places to check advice will be greatly appreciated.
