[Johnson] Johnson Ranger Problem -part 2

[Glen Zook]

Try a different 6AQ5.  Even though it "tests" good it
still may not function properly in the circuit.

Also, on a Ranger that I had in for service a few
weeks ago the screen resistor had "opened up" and it
would do "screwy" things.

When the 6AQ5 is removed the final amplifier should
draw too much current when drive is removed (like
between characters on CW).  At least that is what
happened in the Rangers that I have worked on lately.

Gary, you gave me a huge hint. I removed the Damper
Tube -6AQ5...and without the tube, the transmitter
works perfectly, including the nuturalization issue. I
have normal plate voltage and full power output.
