:: ".125ma?" How can you even read the meter that low? Do you mean
"125ma?" Is this without keying the amplifier or applying RF drive? Or
with keying the amp, and without RF drive? Or with both? Or what?

::Ditto the questions above. The 374's plate current meter is 1
ampere, it's impossible to read .125ma. Maybe you mean 125ma? That's
"idling?" Explain the exact conditions.

::I don't get the question. There's an OFF switch. That should
turn the amp off.

::Normally the 374 runs with very little idling plate current and
idling grid current is "zero." If you have idling grid current, that's a
problem.
