This aint rocket science at my shack.
I have a pair of trusty old 813's in grounded grid with 3200 Volts on the
plates. I drive them with my Ranger all the time with no problems at all.
I always tune the ranger up to full power into a either a dummy, or my
dipole. THEN switch the 813's into the line and then quickly dip the ranger.
It usually will dip back to about 80'mils. I leave it right there and get
legal power out of the 813's.
If I want to bring the Ranger back up to full power, I can and it will drive
those 813's to 600 watts and sounds great.
I have been using this combination for 6 years and many of you have heard me
If I DO bring the ranger back up to 120 mils, I have to be careful of the
audio drive, as it will tend to start to distort if the gain is up to high.
But if I leave the Ranger at 80 mils, it works fine and I work coast to coast!
Gotta love those old 813's!
