[Amps] Plate choke resonanse and safe operation

[OZ1AXG Flam]

the RFC is Installed

I will try to measure the resonans again. For 27 MHZ i did the measurement 3 
times. A grid dip meter is not the most accurate instrument, so i will try 
it again. but how close is "safe" ? what would the symptoms be at tuneup if 
resonans is close by ?

Then old RFC fried (broke a wire) when i accendential tranmitted 125 watt 
(1/2 second) in the amplifier. Had forgotten to reduce the drive before 
tuning :=(  This has happened before on other band - but this was a first 
for 30 meters ...
