Hi Guys,

Here's a question I've always wondered about.

"Is the rf voltage in a final tank coil equally distributed across the coil?"

The reason I'm asking this is I'm building an amp that will use
approximately 5500v B+. I'm probably going with a roller inductor (30 amp
30mH Gates), due to fear of the arcing contact caper in a band switch.  The
amp would be capable of about 5kw with a 500watt driver, to be totally
honest, so I'm selling my Centaur to avoid temptation.

"Considering the voltages on the coil, and the potential power level, does
a band switch exist to reliably switch these voltages?"
