"Sand" could easily be best for the constant current sink (CCS), say the 10M45S integrated circuit. If 100% "hollow state" is desired, a multi-grid type whose current handling capability is appropriate gets the nod. Ground g2 and employ a negative rail that's "tall" enough to ensure correct operation. A member over at DIY Audio suggested regulating the negative rail, to emphasize multi-grid constant current behavior. The negative rail is g2 B+.

The previously linked 6J6 data sheet suggested 8.5 mA./triode as being the "typical" "idle" current. A type that can comfortably handle a 17+ mA. plate current is needed for the CCS. The 6CL6 is quite adequate for the role.
