2.0 μF. is large enough to take you out of critical current territory and the good regulation that goes with it. :>( What vacuum rectifier are you using? A 5R4 drops a whopping 67 V., when delivering its 250 mA. maximum.
If you want critical current behavior, you need to find a lower forward drop vacuum rectifier or switch to SS rectified B+. The value of the "fudge factor" cap. needs to be under 1 μF.
