OK I'm probably too conservative, but I can't support the smell of the "hot 
component" ... For me a L7 (like a SB220, TL922, L4, etc) is dimensionned for a 
good K in SSB... not more!
Also depends if you are a CQ'er or a S&P'er... it makes a lot of difference on 
the duty cycle - especialy when the rate is low! 
For a PA, my principle is that the "brick-on-the-key" power gives you a 
reliable TTY contest operating power... anything above this is only "CQ and 
pray !". 

I think the following rule can also be applied to any part of the TX-chain 
(from the transceiver to the antenna): A reliable limit is given by SSBrating/4 
or by CWrating/2; anything above this is only "possible". But once again this 
is a conservative approach... 

Scott,
Googling around I found this interesting page:
http://lists.contesting.com/archives/html/CQ-Contest/1996-05/msg00055.html
The AMP reflector on contesting.com is also a very useful source of 
information... just type a brand / model in the search engine, and you 'll get 
a lot of informations from this eqt users...


Happy new year to all and cu next year in the round-up...
