 A normal SB-200 running on 220 with good tubes will
run under full load about 2000 volts at 500 ma. and about
80 ma of grid current. My SB-200 will show 650 watts out
on 80 and 40, 600 on 20 and 15 and about 500 watts on 10
meters measured with a Bird 43 into a dummy.
 I would stay away from the Svetlana tubes, first choice
is Cetron, then Taylor. I have used Taylor's and have
no complaints.
