Hello Antonio.Basically Jason and i are saying the same thing.
An horizontal line would represent an infinite anode load at all frequencies. The best CCS get close to this, having an impedance in the tens of megohm range. This is not the case for a choke, because its impedance varies with frequency: Z=2*pi*f*L
For your 40H choke:
At 20Khz: 5 026 548 Ohm, pretty close to an horizontal line; but at 20 Hz: 5027 Ohm. Not so much of an infinite load... That is why i said that 40H was a lowish value. For example, my 260H choke has an impedance of 32673Ohm at 20Hz. I have a spare pair of these if you'd like to try them ;o)Good luck!--SomeJoe
