   Solder the large shield between the 6146's and the driver tube to the
chassis with a great big gun/iron or a small torch.

   Pentodes shouldn't need neutralized, mine didn't after I soldered the shield 
down.

   If this bothers you, remove the shield and clean the chassis top and shield 
bottom, add a bit of anti-Ox between them and bolt it back in tight.
