 If you have PROOF, that's one thing but constantly demanding that 
 others provide the proof, calling their statements "manure," or 
 addressing other posters as if they were novices will not be 
 tolerated.  If you do not agree with W8JI's manual for the AL-80 
 it is up to you to prove that it is wrong.  If you believe the 
 3-500Z cannot handle 550 mA for short peaks, put one in a properly 
 constructed and instrumented test fixture and prove it.  Otherwise, 
 accept that "Eimac had no problem at all with the manual telling 
 people they could TUNE to 550mA, and then back drive off until 
 400mA is reached." 
 If you can, show that the tube cannot achieve 550 mA of plate 
 current due to cathode starvation.  Show that when tuned for 
 550 mA of peak plate current and driven for 400 mA the IMD is 
 unacceptable.  Prove that the operation is not consistent with 
 good practice but do not attack the messenger.   
 Manufacturer's spec sheets are guidelines for operation and their 
 maximum ratings ALWAYS contain a safety factor.  Anyone who will 
 design or operate a device will "all parameters at maximum" is a 
 fool but "typical operating conditions" are just that - "typical." 
 I have run broadcast transmitters outside the tube manufacturer's 
 "spec sheet" many times and been completely legal.  In several 
 instances the new parameters became standard practice for the 
 industry and were blessed by the tube manufacturer even though 
 the spec sheets NEVER reflected the practice.

Uh-oh! Looks like the Administrator has fallen into the fray here, preaching 
from his pulpit.

Lets see, is this a case of "absolute power corrupting absolutely..."?
