But, whether or not that is the right value to achieve my parameters, i am not sure as i am pretty much following my other fixed bias amp which had a 50k pot for the voltage adjustment. i admit that the correctly working circuit is not the same as this circuit. This new circuit i chose because it has a fail safe feature. I don't know if it has been vetted by other users. Theoretically, does anyone see why it can not work? I left many of the resistors in the bias circuit unsoldered in anticipation of changes. cheers and thanks for all the suggestions.
