[Amps] IM distortion and such

[Colin Lamb]

Rich asks:

"Can an unloaded tank reach potentials higher than the breakdown  
voltage of its Tune C?"

Yes.  We are not dealing with dc, but waves.  These waves do not necessarily where you expect them or want them to.  The peaks will vary depending upon the frequency and length of components.  It might be easier to imagine standing waves on antennas.  The same thing will apply in tank circuits. 

So, having a plate tuning capacitor that breaks down at 5 kv will not necessarily prevent arcing at a plate switch that is rated a 6 kv.
