[Elecraft] Securing Q3 and Q4 on KPA100

[Unifiedtx@aol.com]

Gary Surrency has suggested that Q3 and Q4 be secured to the heat sink with a 
thick fiber washer (like the speaker washer) rather than the split washer 
that can bite into the plastic transistor body and damage it.  Fiber washers 
about the size of the speaker washers can be found at Home Depot.  The 
washers to use are the #4 x .032".  The hole in these washers are slightly 
larger than the screw diameter which should let the washer seat properly if 
the transistor is not in perfect alignment with the PCB hole.  I am not using 
the split washer on top of the fiber washer, and I don't believe Gary uses 
the split washer on top of the fiber washer either.  If these screws are 
tightened with normal torque, they will stay put.  Roy Morris  W4WFB  K2/100
