When I ask Kevin what the winding capacitance of the LL1670 is he answered 223pF.
This would be added to the Miller of the tube.
On the other hand Mike said the measured capacitance of the BCP-16 GC is only 15pF.
I should buy a pair.
On the other hand my 5687 driver tube is CCS loaded and the 270k ohms grid resistor gives a pretty horizontal load line and I don't have enough gain in my system to ever overload the output tube.
So, as with most things, the particular circumstance dictates what's needed and what's not.
