RF grounded screens (Eimac socket WITH bypass) + total 10K resistor(s) hung
from screen to ground + swamped grid circuit = don't need no stinkin
neutralization. Period.
Especially at 6m.

I used SK-630 sockets on four 4CX250Bs on six without neutralization.

I think the secret to a stable six meter amp is well RF grounded screens.
