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! de Andy, KD3RF / VE2DXY -- View this message in context: http://elecraft.365791.n2.nabble.com/KPA-500-CQWW-flawless-performance-tp6942607p6976628.html Sent from the Elecraft mailing list archive at Nabble.com. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
