All the published articles Ive read are pure garbage, or worse than Edisonian 
as Tom might say. I get LOTS of SB-200 and 220's in here from guys who have 
tried to follow those articles as well as some who have bought other 
conversions that blow up when they change tubes or make a mistake in tuning.

6M Conversions since 1964

    Converting the SB-200 to a 6M monobander is simple and straightforeward 
    basic design principles are followed. Ive been doing those conversions 
    the late 60's and it is completely stable and repeatable. Power output and 
    efficiency is the same or better than a good stock unit on say 20M.


  Carl, Indeed, the word on the street is that the 572B is not good to 6 
meters, but as you say if it is handled properly it can be made to be rather 
stable and the power in the 700 watts range easily.  I haven't really seen a 
published article that really "gets it right" however.  Lou
