[Elecraft] KPA500 finals blown

[Clay Autery]

Thermal design and supplementation of existing designs is not often a
trivial task.  To do it properly, requires a well-reasoned, step-by-step
plan that is both scientifically and mathematically driven AND limited. 
One cannot break the laws of physics...  you can sometimes appear to
bend them, but you can't break 'em.

And on a fine piece of equipment like the KPA500, it would be all but
criminal NOT to do it right.  I've not had the privilege to see the
inside of one yet, but I do have a great deal of experience solving
thermal control problems.

Contact me offline if you're serious about this AND you have verified
that the amp is 100% operational and performing within specs.  Thermal
design is not a band-aid for ailing equipment.
