Say I'm looking at a standard cathode follower gain stage with too much gain: what is the best way to reduce the gain? Between throwing a voltage divider on the output side and changing the value of the grid/cathode resistors, it would seem that the voltage follower route would decrease the S/N ratio but altering the grid/cathode resistor values would be more work to calculate.
Is there an easy way to calculate the change in gain from varying the grid/cathode resistors or does this throw the whole thing off too much to make it easy? Thanks in advance!!!
