and using heatsink compound and proper hardware (6x32 bolt with the lockwasher and a nut on it) to mount
the resistor. The resistor connects across the neutralizing capacitor. Fig. 18 Lead lengths are not especially
critical. Ground the tube grids directly using solder lugs provided in the kit and solder the GDT's in as shown in
Fig. 18.
