crystal from socket). Under these conditions plate current should exceed
200 milliamperes, grid current and power output should drop to "0".
NOTE: WHEN MAKING THIS TEST DO NOT KEY TRANSMITTER FOR
MORE THAN A FEW SECONDS AT A TIME.
e) If preceding step reveals no self oscillation leave C158 at its present
setting. If oscillation persists reduce capacity of neutralization capacitor
in small steps until self oscillation stops. Always re-adjust grid and plate
tuning of the final stage for optimum performance when a re-adjustment of
the neutralization capacitor has been made.
