The BCP-16 Ni grid choke has over 3000H inductnace. I don't remember the DCR exactly, but it's something like 3k ohms. The goal is a flat freq response, but I wouldn't be opposed to a slight bass lift. My altecs could use some help there. I was thinking of testing the circuit with a square wave and looking at the signal on the 45 grid. Then fiddle with resitors across the grid choke to try and damp out any ringing. That said, I've never heard anyone suggest that a resistor was needed across the BCP-16.
