I wish I had some other people to pester with my constant stream of questions, but I don't know a better place to ask...
which of the following is the best solution for an attenuator between a common cathode stage and a cathode follower?
Gut feeling says number 2. It doesn't need as large capacitor, and needs only one of them. Drawback is that pot (or MBB rotary switch) is referenced to a relatively high voltage, but at least it'll work. Notice I compensated plate resistor so total parallel resistance stays at 27k with the 100k pot.
Number 3 I was not sure of, would it even work? It also has the problem of being referenced to a relatively high voltage.
Or maybe there is an even better option I could not think of?
Thanks,
Mike
