do you need a decoupling cap between the 20hy choke and the CCS?putting two constant current devices in series often causes lots of problems.
actually do you need the 20hy choke at all???
do you also want a decoupling cap on your fixed bias supply???
and finally the single dropping resistor will not drop anything unless current is being drawn, so the grid will be at the negative value of the B+ potential.
you need another resistor to ground to form the voltage divider, and actually a series resistor with a pot to ground will make the whole thing adjustable...
