Classic 3-1000z circuits have the grid grounded,
the cathode using a tuned circuit. For best operation
degeneration resistors in the cathode as described
are good practice.
-
Parasitic Suppressors are pretty much a "must
have." Careful construction of the final box is
prudent to prevent VHF oscillation/activity.
-
Snooping around the completed circuit with
a grid dip meter is a great idea. Check the box
close in the lower VHF regions.
