I bet it is a hi buck audio system, been working on mine, liquid N cooled, 
10Kw into 52 OHM speakers fed with 1 7/8 inch gold plated hard line, the 
difference in sound is amazing!!  Its all in keeping the SWR on the speaker 
feeds low!  Bernie W8RPW

The interesting thing here is that in a half watt resistor of
500,000 mega ohms, the current must be less that 1 micro amps and that would
be at a voltage of 500,000 volts.  That resistor would need to be longer
than a couple of inches to prevent it for arcing around the outside and as
someone said in a glass vacuum chamber.

So curiosity has me.  Maybe I missed it, but what is its intended
use.  If for a high voltage meter for measuring static charge, I bet a 0-1
micro amp movement will cost more than your gasoline bill.
