Couple more things. Is this bent gun tube? Bush bumph says no ion trap but Mullard data says it needs one. If the gun structure is obviously wonky looking then there should be an ion trap magnet which adds another complication.

Also sounds like the EHT is a bit weedy. Should be a good zap from the EY86 anode. Then a rather weak looking spark from the DC at the EHT connector or EY86 cathode.
