"...I would like to get the group opinion on
- using a long/big normal air wound coil to get around 1 mH (coil not
involved in "matching" i.e. impedance well above circuit impedance at the
anode. 1 inch wide/several inch long/500turns)...(etc)"


Yes, I think that solenoid above is the best choice. Pi-wound can slam the 
sections together if a bang happens. Ferrite I'm leery about, but would like 
to experiment more. One inch by 600 turns of #24 is ideal...it ought to be 
essentially invisible to the tank circuit.
