€  On 10m, with too much L-sup, high anode supply potential, and AØ/NØN, 
R-sup can melt-down.  However, when R-sup fails on 15m, 20m, 40m or 80m, 
there is seemingly no way that enough fundamental potential could be 
developed across L-sup to damage R-sup.  

>My argument was not based at all on disputing Ohms law.  
>You seem to think that resistors fail becuase of parasitics.  I disagree 

€  Then you need to demonstrate how much fundamental dissipation could 
have existed on the freq. where a R-sup  failure took place.

€  The *QST* article gives a non-calculus method of determining R-sup 
dissipation.  I fail to see how this article is a red-herring when we are 
discussing R-sup dissipation.
