[Elecraft] Update & final score Re: KPA 500 CQWW flawless performance

[KD3RF]

Hi Johnny:

The THP is an older tube model running a pair of 4X150's and like all tube
amps it was less efficient, and produced only 350 - 400 watts on the 15 and
10 meter bands with 60 watts drive.  On 20, 40 and 80 meters the THP
produced more power, but still not as good as the KPA500. 

The KPA500 on the other hand was 500 watts ++ on every band, from 10 meters
to 160 meters.

For CQWW SSB 2012 we will retire the THP and hopefully have a second KPA500
in the station!
