On re-reading my own post, this paragraph doesn't convey what I meant:

Should read:

Now turn off, do your mod. Run the filaments only if you can, or disconnect
the entire B+ to all transmit stages. Start your oscillator, key the
transmitter
or ensure the keying line is grounded, and check the meter reading. If you
get the same level of current or more, you have enough grid drive.

Sorry 'bout that.
