[Amps] High temp magnet wire?

I believe Bill is correct. However, since K3LR's intended use is to 
repair a bad monoband 40m plate choke, the temperature specifications of 
the wire are not important. I'm sure Bill would agree with me that a 
properly designed plate choke should never run hot. The only temperature 
rise should be from the radiated heat of nearby tubes. When a plate 
choke shows thermal damage, it is usually caused by an undesired 
self-resonance, which is normally not an issue on a monoband amplifier.
