[Amps] Anode clearance and Chassis WANTED

[George]

I don't like the 1 inch spark plug anode being that close.  If you ever have
a parasitic problem...look out.  Maybe some corona dope on the top of the
cap and the bottom of the lid would give you a little more safety.  I once
painted a variable cap with that stuff and it worked nicely.

|I am building a 4-1000A linear and will have 4KV on the anode.  What is
|the MINIMUM clearance I must have from the anode to the top of the metal
|cabinet?  It looks like it will be about 1" in my present configuration.
| Will that be sufficient to prevent any problems?
|
|I am looking for a chassis 14"x13.25"x3.25".........may have to go to a
|shorter one if the answer to above question is NO but really need the
|3.25" for the input tuning box to fit.
