In Reply to: Can someone school me on cathode feedback? posted by twystd on March 24, 2015 at 19:52:28:
It is just feedback that happens to be on the cathode instead of the more common global feedback. Most push pull amps utilize global feedback that is more than 8dB so the driver section in almost any amp schematic you look at will be more than up to the voltage gain task. Your point on the driver current, more current is always better, in any amp. The MC-60 used the Gutsy 12AX7 Cathode follower to put the iron hand of fear into the cathode feedback output section.
