As nothing else changes, I'd suspect a metering issue. Resistors,
switch, or the meter?

Hi All,
I have an Alpha 9500 with an interesting issue. The grid current
slowly falls to near zero (less than 2-3 ma) with constant carrier
input and constant output over a few minutes. The plate current is
constant near 750ma and the output constant at 1500 watts. Can this
be the tube? The meter circuit?
Thanks for your help,
