[Amps] PI-L Thoughts!

Forget messing up the Q, it's gonna drive you to drink...

For 10 meter correction of excess Tune C, you will have to have an inductance in series with the plate lead of the tube... It can be on either side of the blocking capacitors - has to be ahead the tune cap, obviously...
Just from what you say I am guessing around one microhenry will help to swamp the capacity...  This can be done easily with a strap about 3/8" of an inch wide forming a half loop with a diameter roughly of your index finger...
