[ARC5] Receiver Voltages.

[Dennis Monticelli]

I find it interesting that those screen bias resistors are so power
hungry.  For example, at 60V the B+ draw is 10mA with >40% of that from
those resistors.  The tubes are only pulling about 6mA, and a lot of that
low draw is due to the very low screen voltages.
