?  If one is using a pressurized chassis, by drilling a grid of small 
holes in the chassis underneath L1, an updraft is created which cools the 
coil.  Thus, one can use 6% Ag, 94% Sn solder (eutectic 221 degrees C).   
This material is approx. 4 times stronger than Ag/Pb solder, and is more 
conductive too.  // Apparently, Heath had things figured out pretty well 
by putting cooling air on the SB-220 tank and bandswitch.
