BMK2 used in cathode-biased amp
#4
Thank you.

I realized I jotted down the x and o position of the MV switched. It makes sense now. 

One question I have is essentially with the MV in the scheme the grid leaks are variable? . I believe what I have is what they call a "type 2" mv or "post phase". I believe the 220k resistor from the wiper to "o" of the bias adjustment pot is put in to account for this and make it more stable?

For the Rk value I am going to swap it out with a higher than 20percent resistor as you had mentioned. What would be the maximum resistance you would limit at before things would become unstable.

For attachments it could be because I an using my phone to post. I will try again on a PC. Hopefully that should work.
