In Reply to: RE: Current feedback usually raises output impedance FWIW nt posted by cellailuca on October 17, 2024 at 09:03:53

Follow Ups:
Correct, because cathode feedback can not be eliminated without destroying circuit topology and current feedback is only 5 dB.
For sake of completeness the input impedance with and without current feedback is 83 Ohm and 104 Ohm respectively.
A very low value for tube standards.
Thank you for your comments.
