Yep, I think that’s it. I need to get a bit more into the idea that I might actually have some idea what I’m doing.RhythMick wrote: ↑Tue Aug 24, 2021 8:43 pm Going out on a limb, possible someone will correct me. I believe R1 is the series total of the output resistance of the previous stage and the actual resistor. So if the calculators show R1 as 24K and the output resistance is 3K then you need a 21K series resistor.
Zout of previous stage calculated as anode load parallel with the valve plate resistance I think?
Be interesting to see how close I am...
