The grid should dip at the same time as the plate.
You can start neutralizing on 20mtrs then do 15 & 10 mtrs....

Gentlemen: How does one determine if the 807 is in fact neutralized and
is
not having parasitic oscillations? I once had a "Griefkit" DX-35 and the
6146
would runaway on 10 meters. This was evidenced by the fact that the
anode
would quickly turn red hot when keying. This transmitter had no
neutralization capacitor but did have a parasitic suppressor in the
plate
lead. - Thank you for all the comments! - Sherrill W. k4own.
