[Amps] Plate choke failure

[Clark Turner]

Last night while tuning my Amp, 2 x 3-1000Z, into the dummy load on 75 
meters, I accidentally turned the Roller inductor instead of the Antenna 
load Crank.  The two turns counters are side by side and I was not 
paying attention.  Thought you guys might like to see this odd falure.  
The coil sections have shrunk on the form and stacked the wires into a 
tighter band.  I installed this choke myself a month ago and at the time 
got a spare. They used to be identical.
