Sure it is. 7.5mA is what's required on a pair, according to Johnson,
and the boo
CCS rating is 3.5 ma max. per tube
ICAS rating is 4.0 ma max. per tube.

Hi Mike,
You are correct. The max grid current for the Viking II pair of 6146s is
8MA.
Additionaly, the Valiant (3 6146s) calls for 10 mA of grid current.
