200 watts drive? What is the grid current? Excessive to say the least.


 I have seen 11 meter "BOWL" boxes built around the 3-500Z.


 The tube has got so hot from being over driven that the solder in the pins actually melted.


 Now what is the difference in signal strength between 2800 watts and 1500 watts?


 Not trying to start an argument just pointing out that that type of output does not really accomplish anything.


 Better to run the equipment at manufactures specifications and also keep it legal according to the license.
