Thanks Kevin
The bias controls are working as it should I believe. As you mentioned one pot was set too far in the range and so the other had no room. But the adjustment is there. Push pull. Also to note is this circuit seems to work a bit differently than the previous build where I have the SV1.
The only issue now is the MV is still not referenced and so it is not functioning at the moment. I have been trying to figure it out as you mentioned you need to put in a new set of coupling caps to account for the voltage now present at the grid. I can't figure out how to reference it to and where to tie them in. Currently the MV is wide open and the normal volume now acts like an MV.
In the process of trying to figure this all out and understand this bias circuit essentially this bias system is adjusting the voltage potential between the Rk and the control grid 2 of the el84 am I correct? In that case shouldn't there be a variable voltage when I measure between the Rk and the grid pin 2?
