Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

RE: I got a question...

what if the pot i use can not get the AC signal to equalize? I am thinking that the pot has to be a larger value than the bias resistor. Should its value be twice as much as the resistor or ??
Also i calculate the approximate current dissipation in the 6sn7 using the voltage and resistor values in the article by AK. I calulated that to be around 4ma. Would it be better to operate the driver tube at a little higher current? regards.
