Peter,
I found the measurement error. Those currents were for 85W drive from a
different exciter, and the PEP reading was 1025. I cannot find the readings
for 150. I do recall that the voltage stayed at 2500 for both readings so
the current must have gone way over the 400ma per tube to get to 1700.

Very unlikely that measurements were correct, at 1812W input you never will
get 1700W output.
The plate current meter should kick to its stop then

I had an L4B that put out 1700W PEP as measured by an Alpha 4510 wattmeter
using 150 watts drive as read on the exciter meter. The anode voltage was
about 2500 as read on the L4B meter. Also, the grid and plate current
showed 190ma and 725ma respectively, again on the L4B meter.
