Thanks Damir. I was reading TubeCad wrong. It's redundant. It's states the F-3db point for a given circuit and then states the capacitance reactance in ohms as the Zin. Knowing the source inpedance and the F-3db point I can calculate the CR but the program gives it anyway. It just does not make it clear. Naz helped me with this.

Thanks....Tre'
