Hi Rod..just got back from the NC trip....280 messages in the que!
A 200 with good tubes and a stiff 240V line will output 700-800W with
100W of drive. For intermittent operation this will not overheat the
xfmr. For contesting, etc, it is best to run about 600W.
With a new pair of Chinese tubes and 120W of drive I obtained 900W from a
6M conversion but that is really pushing the PS.

$300 is the upper limit for one in top condx. I buy them regularly for
$250-275.
